* 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6: (38 commits)
  direct I/O fallback sync simplification
  ocfs: stop using do_sync_mapping_range
  cleanup blockdev_direct_IO locking
  make generic_acl slightly more generic
  sanitize xattr handler prototypes
  libfs: move EXPORT_SYMBOL for d_alloc_name
  vfs: force reval of target when following LAST_BIND symlinks (try #7)
  ima: limit imbalance msg
  Untangling ima mess, part 3: kill dead code in ima
  Untangling ima mess, part 2: deal with counters
  Untangling ima mess, part 1: alloc_file()
  O_TRUNC open shouldn't fail after file truncation
  ima: call ima_inode_free ima_inode_free
  IMA: clean up the IMA counts updating code
  ima: only insert at inode creation time
  ima: valid return code from ima_inode_alloc
  fs: move get_empty_filp() deffinition to internal.h
  Sanitize exec_permission_lite()
  Kill cached_lookup() and real_lookup()
  Kill path_lookup_open()
