[git pull] more vfs bits

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

	Unfortunately, it looks like xattr series will have to wait until
the next cycle ;-/  This pile contains 9p cleanups and fixes (races in
v9fs_fid_add(), etc.), fixup for nommu breakage in shmem.c, several cleanups
and a bit more file_inode() work.  Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus

Shortlog:
Al Viro (13):
      selinux: opened file can't have NULL or negative ->f_path.dentry
      more file_inode() open-coded instances
      9p: don't bother with private lock in ->d_fsdata; dentry->d_lock will do just fine
      9p: turn fid->dlist into hlist
      v9fs: get rid of v9fs_dentry
      9p: v9fs_fid_add() can't fail now
      9p: double iput() in ->lookup() if d_materialise_unique() fails
      9p: untangle ->lookup() a bit
      9p: make sure ->lookup() adds fid to the right dentry
      9p: if v9fs_fid_lookup() gets to asking server, it'd better have hashed dentry
      cache the value of file_inode() in struct file
      fix nommu breakage in shmem.c
      constify path_get/path_put and fs_struct.c stuff
