  SELinux: introduce path_has_perm
  flex_array: allow 0 length elements
  flex_arrays: allow zero length flex arrays
  flex_array: flex_array_prealloc takes a number of elements, not an end
  SELinux: pass last path component in may_create
  SELinux: put name based create rules in a hashtable
  SELinux: generic hashtab entry counter
  SELinux: calculate and print hashtab stats with a generic function
  SELinux: skip filename trans rules if ttype does not match parent dir
  SELinux: rename filename_compute_type argument to *type instead of *con
  SELinux: fix comment to state filename_compute_type takes an objname not a qstr
  SMACK: smack_file_lock can use the struct path
  LSM: separate LSM_AUDIT_DATA_DENTRY from LSM_AUDIT_DATA_PATH
  LSM: split LSM_AUDIT_DATA_FS into _PATH and _INODE
  SELINUX: Make selinux cache VFS RCU walks safe
  SECURITY: Move exec_permission RCU checks into security modules
  SELinux: security_read_policy should take a size_t not ssize_t
