2010-05-21suppress warning: "quotatypes" defined but not usedSergey Senozhatsky1-0/+2
Suppress compilation warning: "quotatypes" defined but not used. quotatypes is used only when CONFIG_QUOTA_DEBUG or CONFIG_PRINT_QUOTA_WARNING is/are defined. Signed-off-by: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>
2010-05-21ext3: Fix waiting on transaction during fsyncJan Kara2-12/+10
log_start_commit() returns 1 only when it started a transaction commit. Thus in case transaction commit is already running, we fail to wait for the commit to finish. Fix the issue by always waiting for the commit regardless of the log_start_commit return value. Signed-off-by: Jan Kara <jack@suse.cz>
2010-05-21jbd: Provide function to check whether transaction will issue data barrierJan Kara3-2/+42
Provide a function which returns whether a transaction with given tid will send a barrier to the filesystem device. The function will be used by ext3 to detect whether fsync needs to send a separate barrier or not. Signed-off-by: Jan Kara <jack@suse.cz>

2010-05-21BKL: Remove BKL from ext2 filesystemJan Blunck2-16/+0
The BKL is still used in ext2_put_super(), ext2_fill_super(), ext2_sync_fs() ext2_remount() and ext2_write_inode(). From these calls ext2_put_super(), ext2_fill_super() and ext2_remount() are protected against each other by the struct super_block s_umount rw semaphore. The call in ext2_write_inode() could only protect the modification of the ext2_sb_info through ext2_update_dynamic_rev() against concurrent ext2_sync_fs() or ext2_remount(). ext2_fill_super() and ext2_put_super() can be left out because you need a valid filesystem reference in all three cases, which you do not have when you are one of these functions. If the BKL is only protecting the modification of the ext2_sb_info it can safely be removed since this is protected by the struct ext2_sb_info s_lock.

2010-05-21ext2: Add ext2_sb_info s_lock spinlockJan Blunck4-1/+39
Add a spinlock that protects against concurrent modifications of s_mount_state, s_blocks_last, s_overhead_last and the content of the superblock's buffer pointed to by sbi->s_es. The spinlock is now used in ext2_xattr_update_super_block() which was setting the EXT2_FEATURE_COMPAT_EXT_ATTR flag on the superblock without protection before. Likewise the spinlock is used in ext2_show_options() to have a consistent view of the mount options. This is a preparation patch for removing the BKL from ext2 in the next patch.

2010-05-21ext2: Move ext2_write_super() out of ext2_setup_super()Jan Blunck1-3/+5
Move ext2_write_super() out of ext2_setup_super() as a preparation for the next patch that adds a new lock for superblock fields. Signed-off-by: Jan Blunck <jblunck@suse.de> Signed-off-by: Jan Kara <jack@suse.cz>
2010-05-21ext2: Fold ext2_commit_super() into ext2_sync_super()Jan Blunck1-19/+9
Both function originally did similar things except that ext2_sync_super() is returning after the call to sync_dirty_buffer(sbh). Therefore this patch adds a wait flag to tell ext2_sync_super() if it has to call sync_dirty_buffer() to wait for in-progress I/O to finish.

2010-05-21ext2: Remove duplicate code from ext2_sync_fs()Jan Blunck1-7/+0
Depending in the state (valid or unchecked) of the filesystem either ext2_sync_super() or ext2_commit_super() is called. If the filesystem is currently valid (it is checked), we first mark it unchecked and afterwards duplicate the work that ext2_sync_super() is doing later. Therefore this patch removes the duplicate code and calls ext2_sync_super() directly after marking the filesystem unchecked.

2010-05-21ext2: Set the write time in ext2_sync_fs()Jan Blunck1-1/+1
This is probably a typo since the write time should actually be updated by ext2_sync_fs() instead of the mount time. Signed-off-by: Jan Blunck <jblunck@suse.de> Signed-off-by: Jan Kara <jack@suse.cz>
2010-05-21ext2: Use ext2_clear_super_error() in ext2_sync_fs()Jan Blunck1-17/+3

2010-05-21ext3: init statistics after journal recovery v2Dmitry Monakhov1-23/+21

2010-05-21ext2: remove useless call to brelse() in ext2_free_inode()Francis Moreau1-5/+4

2010-05-21ext2: Avoid loading bitmaps for full groups during block allocationJan Kara1-0/+6
There is no point in loading bitmap for groups which are completely full. This causes noticeable performance problems (and memory pressure) on small systems with large full filesystem (http://marc.info/?l=linux-ext4&m=126843108314310&w=2). Port of the same ext3 patch.

2010-05-21Fix networking tree iscsi_tcp.c mis-mergeLinus Torvalds1-1/+1
The removal of the 'waitqueue_active()' test in commit d7d05548a6 ("[SCSI] iscsi_tcp: fix relogin/shutdown hang") got incorrectly resolved by David when he back-merged the main git tree into the networking tree in commit 278554bd65 ("Merge branch 'master' of master.kernel.org:..."). There was a content conflict due to 'sock->sk->sk_sleep' being changed into 'sk_sleep(sock->sk)' in the networking tree, but David didn't pick up the iscsi change from the main tree.

2010-05-20usb-storage: always print quirksFelipe Contreras1-3/+6
Right now quirks are printed only when the are manually overriden with the module parameters. It's not so useful to remind the user that his parameters are correctly applied; what is useful is to print out the quirks the user is not aware are being applied. So let's do the smart thing and print the quirks when they are present.
