[git pull] VFS patches (second series)

[git pull] VFS patches (second series)

[Al Viro]

	More namespace.c sanitizing (saner locking rules, further trimming
of stack footprint).  Preparation for mountinfo merge (allowing seq_file
->show() to tell seq_file that output for this entry is to be discarded).
A couple of fixes - one for long-standing race in /proc/*/fd readdir,
another for breakage introduced on pipe() failure exit in ro-bind series
(this one is probably the most urgent in the entire pile).  And misc
cleanups...

	There will be probably 3 or 4 more series in this cycle - this
is not the last one...

Shortlog:
Al Viro (9):
      move a bunch of declarations to fs/internal.h
      lock exclusively in collect_mounts() and drop_collected_mounts()
      switch a bunch of LSM hooks from nameidata to path
      get rid of more nameidata passing in namespace.c
      umount_tree() will unhash everything itself
      teach seq_file to discard entries
      double-free of inode on alloc_file() failure exit in create_write_pipe()
      proc_readfd_common() race fix
      get rid of __exit_files(), __exit_fs() and __put_fs_struct()

Btw, your last series introduced a warning (fs/xattr.c - unused 'out_fput' 
label), so I'm hoping that one has some reason for it? Or can we just get 
that thing removed?

	The latter; will do in the next batch.

Just curious... do you plan to merge your changes to anon_inodes for
2.6.26?

Thanks,
  Roland

As soon as kvm.git gets merged...
