hfsplus: rework processing of hfs_btree_write() returned error

2012-12-21T01:40:19Z

Add to hfs_btree_write() a return of -EIO on failure of b-tree node searching. Also add logic ofor processing errors from hfs_btree_write() in hfsplus_system_write_inode() with a message about b-tree writing failure.

fs: push rcu_barrier() from deactivate_locked_super() to filesystems

2012-10-03T01:35:55Z

There's no reason to call rcu_barrier() on every deactivate_locked_super(). We only need to make sure that all delayed rcu free inodes are flushed before we destroy related cache. Removing rcu_barrier() from deactivate_locked_super() affects some fast paths. E.g. on my machine exit_group() of a last process in IPC namespace takes 0.07538s. rcu_barrier() takes 0.05188s of that time. Signed-off-by: Kirill A.

hfsplus: get rid of write_super

2012-07-22T19:58:04Z

This patch makes hfsplus stop using the VFS '->write_super()' method along with the 's_dirt' superblock flag, because they are on their way out. The whole "superblock write-out" VFS infrastructure is served by the 'sync_supers()' kernel thread, which wakes up every 5 (by default) seconds and writes out all dirty superblocks using the '->write_super()' call-back. But the problem with this thread is that it wastes power by waking up the system every 5 seconds, even if there are no diry superblocks, or there are no client file-systems which would need this (e.g., btrfs does not use '->write_super()'). So we want to kill it completely and thus, we need to make file-systems to stop using the '->write_super()' VFS service, and then remove it together with the kernel thread. Tested using fsstress from the LTP project. Signed-off-by: Artem Bityutskiy Signed-off-by: Al Viro

hfsplus: remove useless check

2012-07-22T19:58:03Z

This check is useless because we always have 'sb->s_fs_info' to be non-NULL. Signed-off-by: Artem Bityutskiy Signed-off-by: Al Viro

hfsplus: amend debugging print

hfsplus: make hfsplus_sync_fs static

2012-07-22T19:58:01Z

vfs: Rename end_writeback() to clear_inode()

2012-05-06T05:43:41Z

After we moved inode_sync_wait() from end_writeback() it doesn't make sense to call the function end_writeback() anymore. Rename it to clear_inode() which well says what the function really does - set I_CLEAR flag. Signed-off-by: Jan Kara Signed-off-by: Fengguang Wu
