2012-01-09dcache: use a dispose list in select_parentDave Chinner1-42/+21
select_parent currently abuses the dentry cache LRU to provide cleanup features for child dentries that need to be freed. It moves them to the tail of the LRU, then tells shrink_dcache_parent() to calls __shrink_dcache_sb to unconditionally move them to a dispose list (as DCACHE_REFERENCED is ignored). __shrink_dcache_sb() has to relock the dentries to move them off the LRU onto the dispose list, but otherwise does not touch the dentries that select_parent() moved to the tail of the LRU. It then passses the dispose list to shrink_dentry_list() which tries to free the dentries. IOWs, the use of __shrink_dcache_sb() is superfluous - we can build exactly the same list of dentries for disposal directly in select_parent() and call shrink_dentry_list() instead of calling __shrink_dcache_sb() to do that. This means that we avoid long holds on the lru lock walking the LRU moving dentries to the dispose list We also avoid the need to relock each dentry just to move it off the LRU, reducing the numebr of times we lock each dentry to dispose of them in shrink_dcache_parent() from 3 to 2 times. Further, we remove one of the two callers of __shrink_dcache_sb(). This also means that __shrink_dcache_sb can be moved into back into prune_dcache_sb() and we no longer have to handle referenced dentries conditionally, simplifying the code.

2012-01-09tracing/mm: Move include of trace/events/kmem.h out of header into slab.cSteven Rostedt2-2/+2
Including trace/events/*.h TRACE_EVENT() macro headers in other headers can cause strange side effects if another trace/event/*.h header includes that header. Having trace/events/kmem.h inside slab_def.h caused a compile error in sparc64 when changes were done to some header files. Moving the kmem.h trace header out of slab.h and into slab.c fixes the problem. Note, both slub.c and slob.c already include the trace/events/kmem.h file. Only slab.c had it missing.

2012-01-09ext{3,4}: Fix potential race when setversion ioctl updates inodeDjalal Harouni2-2/+10
The EXT{3,4}_IOC_SETVERSION ioctl() updates i_ctime and i_generation without i_mutex. This can lead to a race with the other operations that update i_ctime. This is not a big issue but let's make the ioctl consistent with how we handle e.g. other timestamp updates and use i_mutex to protect inode changes.

2012-01-09ext3: Don't warn from writepage when readonly inode is spotted after errorJan Kara1-3/+21
WARN_ON_ONCE(IS_RDONLY(inode)) tends to trip when filesystem hits error and is remounted read-only. This unnecessarily scares users (well, they should be scared because of filesystem error, but the stack trace distracts them from the right source of their fear ;-). We could as well just remove the WARN_ON but it's not hard to fix it to not trip on filesystem with errors and not use more cycles in the common case so that's what we do.

2012-01-09jbd: Remove j_barrier mutexJan Kara3-21/+22
j_barrier mutex is used for serializing different journal lock operations. The problem with it is that e.g. FIFREEZE ioctl results in process leaving kernel with j_barrier mutex held which makes lockdep freak out. Also hibernation code wants to freeze filesystem but it cannot do so because it then cannot hibernate the system because of mutex being locked. So we remove j_barrier mutex and use direct wait on j_barrier_count instead. Since locking journal is a rare operation we don't have to care about fairness or such things.

2012-01-09reiserfs: Force inode evictions before umount to avoid crashJeff Mahoney1-10/+14
This patch fixes a crash in reiserfs_delete_xattrs during umount. When shrink_dcache_for_umount clears the dcache from generic_shutdown_super, delayed evictions are forced to disk. If an evicted inode has extended attributes associated with it, it will need to walk the xattr tree to locate and remove them. But since shrink_dcache_for_umount will BUG if it encounters active dentries, the xattr tree must be released before it's called or it will crash during every umount. This patch forces the evictions to occur before generic_shutdown_super by calling shrink_dcache_sb first. The additional evictions caused by the removal of each associated xattr file and dir will be automatically handled as they're added to the LRU list.

2012-01-09udf: Fix deadlock when converting file from in-ICB one to normal oneJan Kara2-6/+21
During BKL removal in 2.6.38, conversion of files from in-ICB format to normal format got broken. We call ->writepage with i_data_sem held but udf_get_block() also acquires i_data_sem thus creating A-A deadlock. We fix the problem by dropping i_data_sem before calling ->writepage() which is safe since i_mutex still protects us against any changes in the file. Also fix pagelock - i_data_sem lock inversion in udf_expand_file_adinicb() by dropping i_data_sem before calling find_or_create_page().

2012-01-09ext2: Fix error handling on inode bitmap corruptionJan Kara1-2/+5
When insert_inode_locked() fails in ext2_new_inode() it most likely means inode bitmap got corrupted and we allocated again inode which is already in use. Also doing unlock_new_inode() during error recovery is wrong since the inode does not have I_NEW set. Fix the problem by informing about filesystem error and jumping to fail: (instead of fail_drop:) which doesn't call unlock_new_inode().
