[git pull] vfs part 2

[Al Viro <viro@ZenIV.linux.org.uk>]

	Next part of VFS stuff: getting do_filp_open() to relative
sanity.  There will be more piles (the next one is dealing with
write_inode mess, in an hour or so).  Please, pull from 
git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ for-linus

Shortlog:
Al Viro (18):
      beginning to untangle do_filp_open()
      gut do_filp_open() a bit more (do_last separation)
      Shift releasing nd->root from do_last() to its caller
      unroll do_last: loop in do_filp_open()
      postpone __putname() until after do_last()
      pull the common predecessors into do_last()
      bail out with ELOOP earlier in do_link loop
      pull more into do_last()
      Don't pass mangled open_flag to finish_open()
      Get rid of passing mangled flag to do_last()
      Leave mangled flag only for setting nd.intent.open.flag
      Pull handling of LAST_BIND into do_last(), clean up ok: part in do_filp_open()
      Kill is_link argument of do_last()
      Unify exits in O_CREAT handling
      Turn do_link spaghetty into a normal loop
      Finish pulling of -ESTALE handling to upper level in do_filp_open()
      Get rid of symlink body copying
      Switch !O_CREAT case to use of do_last()
