Merge branch 'work.icache' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull vfs inode freeing updates from Al Viro:
 "Introduction of separate method for RCU-delayed part of
  ->destroy_inode() (if any).

  Pretty much as posted, except that destroy_inode() stashes
  ->free_inode into the victim (anon-unioned with ->i_fops) before
  scheduling i_callback() and the last two patches (sockfs conversion
  and folding struct socket_wq into struct socket) are excluded - that
  pair should go through netdev once davem reopens his tree"

inode to d_splice_alias() will also do the right thing (equivalent of
d_add(dentry, NULL); return NULL;), so that kind of special cases
also doesn't need a separate treatment.
--
[strongly recommended]
take the RCU-delayed parts of ->destroy_inode() into a new method -
->free_inode(). If ->destroy_inode() becomes empty - all the better,
just get rid of it. Synchronous work (e.g. the stuff that can't
be done from an RCU callback, or any WARN_ON() where we want the
stack trace) *might* be movable to ->evict_inode(); however,
that goes only for the things that are not needed to balance something
done by ->alloc_inode(). IOW, if it's cleaning up the stuff that
might have accumulated over the life of in-core inode, ->evict_inode()
might be a fit.
Rules for inode destruction:
* if ->destroy_inode() is non-NULL, it gets called
* if ->free_inode() is non-NULL, it gets scheduled by call_rcu()
* combination of NULL ->destroy_inode and NULL ->free_inode is
treated as NULL/free_inode_nonrcu, to preserve the compatibility.
Note that the callback (be it via ->free_inode() or explicit call_rcu()
in ->destroy_inode()) is *NOT* ordered wrt superblock destruction;
as the matter of fact, the superblock and all associated structures
might be already gone. The filesystem driver is guaranteed to be still
there, but that's it. Freeing memory in the callback is fine; doing
more than that is possible, but requires a lot of care and is best
avoided.
