Merge branches 'work.misc' and 'work.dcache' of git://git.kernel.org/pub/scm/linux...

Pull misc vfs updates from Al Viro:
 "Misc cleanups from various folks all over the place

  I expected more fs/dcache.c cleanups this cycle, so that went into a
  separate branch. Said cleanups have missed the window, so in the
  hindsight it could've gone into work.misc instead. Decided not to
  cherry-pick, thus the 'work.dcache' branch"

* 'work.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  fs: dcache: Use true and false for boolean values
  fold generic_readlink() into its only caller
  fs: shave 8 bytes off of struct inode
  fs: Add more kernel-doc to the produced documentation
  fs: Fix attr.c kernel-doc
  removed extra extern file_fdatawait_range

* 'work.dcache' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  kill dentry_update_name_case()
