Conflicts: drivers/ata/libata-scsi.c include/linux/libata.h Futher merge of Linus's head and compilation fixups. Signed-Off-By: David Howells <dhowells@redhat.com>
2006-12-01ocfs2: implement i_op->permissionTiger Yang3-0/+27
Implement .permission() in ocfs2_file_iops, ocfs2_special_file_iops and ocfs2_dir_iops. This helps us avoid some multi-node races with mode change and vfs operations. Signed-off-by: Tiger Yang <tiger.yang@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: update file system paths to set atimeTiger Yang4-6/+28
Conditionally update atime in ocfs2_file_aio_read(), ocfs2_readdir() and ocfs2_mmap(). Signed-off-by: Tiger Yang <tiger.yang@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: core atime update functionsTiger Yang7-1/+116
This patch adds the core routines for updating atime in ocfs2. Signed-off-by: Tiger Yang <tiger.yang@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: Add splice supportTiger Yang1-50/+137
Add splice read/write support in ocfs2. ocfs2_file_splice_read/write are very similar to ocfs2_file_aio_read/write. Signed-off-by: Tiger Yang <tiger.yang@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: Remove ocfs2_write_should_remove_suid()Mark Fasheh1-15/+1
Use should_remove_suid() instead. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: Remove struct ocfs2_journal_handle in favor of handle_tMark Fasheh20-186/+130
This is mostly a search and replace as ocfs2_journal_handle is now no more than a container for a handle_t pointer. ocfs2_commit_trans() becomes very straight forward, and we remove some out of date comments / code. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: remove handle argument to ocfs2_start_trans()Mark Fasheh11-46/+30
All callers either pass in NULL directly, or a local variable that is already set to NULL. The internals of ocfs2_start_trans() get a nice cleanup as a result. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: remove ocfs2_journal_handle journal fieldMark Fasheh2-3/+0
It is no longer used. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: pass ocfs2_super * into ocfs2_commit_trans()Mark Fasheh11-29/+31
This sets us up to remove handle->journal. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: remove unused handle argument from ocfs2_meta_lock_full()Mark Fasheh14-51/+41
Now that this is unused and all callers pass NULL, we can safely remove it. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: make ocfs2_alloc_handle() staticMark Fasheh2-7/+1
This is no longer used outside of journal.c Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: remove unused ocfs2_handle_add_lock()Mark Fasheh4-117/+2
This gets us rid of a slab we no longer need, as well as removing the majority of what's left on ocfs2_journal_handle. ocfs2_commit_unstarted_handle() has no more real work to do, so remove that function too. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: remove unused ocfs2_handle_add_inode()Mark Fasheh5-67/+0
We can also delete the unused infrastructure which was once in place to support this functionality. ocfs2_inode_private loses ip_handle and ip_handle_list. ocfs2_journal_handle loses handle_list. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: Don't allocate handle early in ocfs2_rename()Mark Fasheh1-8/+1
It isn't used until ocfs2_start_trans() anyway. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: don't use handle for locking in allocation functionsMark Fasheh7-152/+72
Instead we record our state on the allocation context structure which all callers already know about and lifetime correctly. This means the reservation functions don't need a handle passed in any more, and we can also take it off the alloc context. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: don't pass handle to ocfs2_meta_lock in ocfs2_rename()Mark Fasheh1-19/+37

2006-12-01ocfs2: don't pass handle to ocfs2_meta_lock() in localalloc.cMark Fasheh1-44/+40
Take and drop the locks directly. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: remove ocfs2_journal_handle flags fieldMark Fasheh4-32/+4
Callers can set h_sync directly on the handle_t, whether a transaction has been started or not can be determined via the existence of the handle_t on the struct ocfs2_journal_handle. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: have ocfs2_extend_trans() take handle_tMark Fasheh4-10/+6
No reason to use our wrapper struct in this function, so take the handle_t directly. Also fixes a bug where we were incorrectly setting the handle to NULL in case of a failure from journal_restart() Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-12-01ocfs2: remove unused ocfs2_journal_handle fieldMark Fasheh2-7/+1

2006-10-20ocfs2: cond_resched() in ocfs2_zero_extend()Mark Fasheh1-0/+7
The loop within ocfs2_zero_extend() can execute for a long time, causing spurious soft lockup warnings. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-10-20ocfs2: fix page zeroing during simple extendsMark Fasheh1-20/+24
The page zeroing code was missing the region between old i_size and new i_size for those extends that didn't actually require a change in space allocation. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-10-20ocfs2: remove spurious d_count check in ocfs2_rename()Sunil Mushran1-8/+0

2006-10-01[PATCH] r/o bind mounts: clean up OCFS2 nlink handlingMark Fasheh1-20/+19
OCFS2 does some operations on i_nlink, then reverts them if some of its operations fail to complete. This does not fit in well with the drop_nlink() logic where we expect i_nlink to stay at zero once it gets there. So, delay all of the nlink operations until we're sure that the operations have completed. Also, introduce a small helper to check whether an inode has proper "unlinkable" i_nlink counts no matter whether it is a directory or regular inode. This patch is broken out from the others because it does contain some logical changes.

2006-10-01[PATCH] r/o bind mount prepwork: inc_nlink() helperDave Hansen2-7/+7
This is mostly included for parity with dec_nlink(), where we will have some more hooks. This one should stay pretty darn straightforward for now.

2006-10-01[PATCH] r/o bind mounts: unlink: monitor i_nlinkDave Hansen1-2/+2
When a filesystem decrements i_nlink to zero, it means that a write must be performed in order to drop the inode from the filesystem. We're shortly going to have keep filesystems from being remounted r/o between the time that this i_nlink decrement and that write occurs. So, add a little helper function to do the decrements. We'll tie into it in a bit to note when i_nlink hits zero.

2006-10-01[PATCH] Vectorize aio_read/aio_write fileop methodsBadari Pulavarty1-15/+13
This patch vectorizes aio_read() and aio_write() methods to prepare for collapsing all aio & vectored operations into one interface - which is aio_read()/aio_write().

2006-09-27[PATCH] inode-diet: Eliminate i_blksize from the inode structureTheodore Ts'o2-6/+0
This eliminates the i_blksize field from struct inode. Filesystems that want to provide a per-inode st_blksize can do so by providing their own getattr routine instead of using the generic_fillattr() function. Note that some filesystems were providing pretty much random (and incorrect) values for i_blksize.

2006-09-27[PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_privateTheodore Ts'o1-1/+1
The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

2006-09-27[PATCH] Really ignore kmem_cache_destroy return valueAlexey Dobriyan1-3/+1
* Rougly half of callers already do it by not checking return value * Code in drivers/acpi/osl.c does the following to be sure: (void)kmem_cache_destroy(cache); * Those who check it printk something, however, slab_error already printed the name of failed cache. * XFS BUGs on failed kmem_cache_destroy which is not the decision low-level filesystem driver should make.

2006-09-24ocfs2: Teach ocfs2_drop_lock() to use ->set_lvb() callbackMark Fasheh1-31/+28
With this, we don't need to pass an additional struct with function pointer. Now that the callbacks are fully used, comment the remaining API. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: Remove ->unblock lockres operationMark Fasheh1-146/+6
Have ocfs2_process_blocked_lock() call ocfs2_generic_unblock_lock(), which gets to be ocfs2_unblock_lock() now that it's the only possible unblock function. Remove the ->unblock() callback from the structure, and all lock type specific unblock functions. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: move downconvert worker to lockres opsMark Fasheh1-18/+32
This way lock types don't have to manually pass it to ocfs2_generic_unblock_lock(). Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: Remove unused dlmglue functionsMark Fasheh1-103/+0
The meta data unblocking code no longer needs ocfs2_do_unblock_meta() or ocfs2_can_downconvert_meta_lock(), so remove them. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: Have the metadata lock use generic dlmglue functionsMark Fasheh1-1/+31
Fill in the ->check_downconvert and ->set_lvb callbacks with meta data specific operations and switch ocfs2_unblock_meta() to call ocfs2_generic_unblock_lock() Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: Add ->set_lvb callback in dlmglueMark Fasheh1-2/+29
This allows a lock type to set the value block before downconvert. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: Add ->check_downconvert callback in dlmglueMark Fasheh1-1/+18
This will allow lock types to force a requeue of a lock downconvert. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: Check for refreshing locks in generic unblock functionMark Fasheh1-12/+19
