Commit fe64f328 authored by Linus Torvalds's avatar Linus Torvalds

Merge branch 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull more vfs updates from Al Viro:
 "Assorted cleanups and fixes.

  In the "trivial API change" department - ->d_compare() losing 'parent'
  argument"

* 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  cachefiles: Fix race between inactivating and culling a cache object
  9p: use clone_fid()
  9p: fix braino introduced in "9p: new helper - v9fs_parent_fid()"
  vfs: make dentry_needs_remove_privs() internal
  vfs: remove file_needs_remove_privs()
  vfs: fix deadlock in file_remove_privs() on overlayfs
  get rid of 'parent' argument of ->d_compare()
  cifs, msdos, vfat, hfs+: don't bother with parent in ->d_compare()
  affs ->d_compare(): don't bother with ->d_inode
  fold _d_rehash() and __d_rehash() together
  fold dentry_rcuwalk_invalidate() into its only remaining caller
parents 0cbbc422 db20a892

->d_instantiate() uses not just ->getxattr() but ->setxattr() as well.

->d_compare() doesn't get parent as a separate argument anymore. If you
used it for finding the struct super_block involved, dentry->d_sb will
work just as well; if it's something more complicated, use dentry->d_parent.
Just be careful not to assume that fetching it more than once will yield
the same value - in RCU mode it could change under you.
