[git pull] vfs pile 3

[Al Viro]

	Stuff from Jeff Layton, mostly.  Sanitizing interplay between
audit and namei, removing a lot of insanity from audit_inode() mess
and getting things ready for his ESTALE patchset.  Please, pull from
the usual place -
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-linus

Shortlog:
Eric Paris (1):
      audit: make audit_compare_dname_path use parent_len helper

Jeff Layton (19):
      audit: remove unnecessary NULL ptr checks from do_path_lookup
      audit: pass in dentry to audit_copy_inode wherever possible
      audit: no need to walk list in audit_inode if name is NULL
      audit: reverse arguments to audit_inode_child
      audit: add a new "type" field to audit_names struct
      audit: set the name_len in audit_inode for parent lookups
      audit: remove dirlen argument to audit_compare_dname_path
      audit: optimize audit_compare_dname_path
      audit: overhaul __audit_inode_child to accomodate retrying
      vfs: allocate page instead of names_cache buffer in mount_block_root
      acct: constify the name arg to acct_on
      vfs: unexport getname and putname symbols
      vfs: define struct filename and have getname() return it
      audit: allow audit code to satisfy getname requests from its names_list
      vfs: turn do_path_lookup into wrapper around struct filename variant
      vfs: make path_openat take a struct filename pointer
      audit: make audit_inode take struct filename
      vfs: embed struct filename inside of names_cache allocation if possible
      procfs: don't need a PATH_MAX allocation to hold a string representation of an int
