  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
