* affs: get rid of affs_sync_superArtem Bityutskiy2012-07-143-13/+45
| | | | | | | | | | | | | | | | | | This patch makes affs 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.

* affs: stop setting bm_flagsArtem Bityutskiy2012-07-141-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AFFS stores values '1' and '2' in 'bm_flags', and I fail to see any logic when it prefers one or another. AFFS writes '1' only from '->put_super()', while '->sync_fs()' and '->write_super()' store value '2'. So on the first glance, it looks like we want to have '1' if we unmount. However, this does not really happen in these cases: 1. superblock is written via 'write_super()' then we unmount; 2. we re-mount R/O, then unmount. which are quite typical. I could not find good documentation describing this field, except of one random piece of documentation in the internet which says that -1 means that the root block is valid, which is not consistent with what we have in the Linux AFFS driver. Jan Kara commented on this: "I have some vague recollection that on Amiga boolean was usually encoded as: 0 == false, ~0 == -1 == true. But it has been ages..." Thus, my conclusion is that value of '1' is as good as value of '2' and we can just always use '2'. An Jan Kara suggested to go further: "generally bm_flags handling looks strange. If they are 0, we mount fs read only and thus cannot change them. If they are != 0, we write 2 there. So IMHO if you just removed bm_flags setting, nothing will really happen." So this patch removes the bm_flags setting completely. This makes the "clean" argument of the 'affs_commit_super()' function unneeded, so it is also removed.

* fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlersJosef Bacik2011-07-202-2/+8
| | | | | | | | | | | | | | | Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

| | | | | | | | | dcache_inode_lock can be replaced with per-inode locking. Use existing inode->i_lock for this.

* fs: icache RCU free inodesNick Piggin2011-01-071-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCU free the struct inode. This will allow: - Subsequent store-free path walking patch. The inode must be consulted for permissions when walking, so an RCU inode reference is a must. - sb_inode_list_lock to be moved inside i_lock because sb list walkers who want to take i_lock no longer need to take sb_inode_list_lock to walk the list in the first place. This will simplify and optimize locking. - Could remove some nested trylock loops in dcache code - Could potentially simplify things a bit in VM land. Do not need to take the page lock to follow page->mapping. The downsides of this is the performance cost of using RCU. In a simple creat/unlink microbenchmark, performance drops by about 10% due to inability to reuse cache-hot slab objects. As iterations increase and RCU freeing starts kicking over, this increases to about 20%. In cases where inode lifetimes are longer (ie. many inodes may be allocated during the average life span of a single inode), a lot of this cache reuse is not applicable, so the regression caused by this patch is smaller. The cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU, however this adds some complexity to list walking and store-free path walking, so I prefer to implement this at a later date, if it is shown to be a win in real situations. I haven't found a regression in any non-micro benchmark so I doubt it will be a problem. Signed-off-by: Nick Piggin <npiggin@kernel.dk>

| | | | | | | | | | | | | Change d_compare so it may be called from lock-free RCU lookups. This does put significant restrictions on what may be done from the callback, however there don't seem to have been any problems with in-tree fses. If some strange use case pops up that _really_ cannot cope with the rcu-walk rules, we can just add new rcu-unaware callbacks, which would cause name lookup to drop out of rcu-walk mode. For in-tree filesystems, this is just a mechanical change. Signed-off-by: Nick Piggin <npiggin@kernel.dk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is a preparation necessary to remove the BKL from do_new_mount(). It explicitly adds calls to lock_kernel()/unlock_kernel() around get_sb/fill_super operations for filesystems that still uses the BKL. I've read through all the code formerly covered by the BKL inside do_kern_mount() and have satisfied myself that it doesn't need the BKL any more. do_kern_mount() is already called without the BKL when mounting the rootfs and in nfsctl. do_kern_mount() calls vfs_kern_mount(), which is called from various places without BKL: simple_pin_fs(), nfs_do_clone_mount() through nfs_follow_mountpoint(), afs_mntpt_do_automount() through afs_mntpt_follow_link(). Both later functions are actually the filesystems follow_link inode operation. vfs_kern_mount() is calling the specified get_sb function and lets the filesystem do its job by calling the given fill_super function. Therefore I think it is safe to push down the BKL from the VFS to the low-level filesystems get_sb/fill_super operation.
