Subject: Merge tag 'pull-qstr' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=33fc69a05c50f00f1218408a56348bcab95b831d;p=thirdparty%2Fkernel%2Fstable.git

Merge tag 'pull-qstr' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull d_name audit update from Al Viro:
 "Simplifying ->d_name audits, easy part.

  Turn dentry->d_name into an anon union of const struct qsrt (d_name
  itself) and a writable alias (__d_name).

  With constification of some struct qstr * arguments of functions that
  get &dentry->d_name passed to them, that ends up with all
  modifications provably done only in fs/dcache.c (and a fairly small
  part of it).

  Any new places doing modifications will be easy to find - grep for
  __d_name will suffice"

* tag 'pull-qstr' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  make it easier to catch those who try to modify ->d_name
  generic_ci_validate_strict_name(): constify name argument
  afs_dir_search: constify qstr argument
  afs_edit_dir_{add,remove}(): constify qstr argument
  exfat_find(): constify qstr argument
  security_dentry_init_security(): constify qstr argument
