#     Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
#     
#     Pull integrity fixes from Mimi Zohar:
#      "A couple of miscellaneous bug fixes for the integrity subsystem:
#     
#       IMA:
#     
#        - Properly modify the open flags in order to calculate the file hash.
#     
#        - On systems requiring the IMA policy to be signed, the policy is
#          loaded differently. Don't differentiate between "enforce" and
#          either "log" or "fix" modes how the policy is loaded.
#     
#       EVM:
#     
#        - Two patches to fix an EVM race condition, normally the result of
#          attempting to load an unsupported hash algorithm.
#     
#        - Use the lockless RCU version for walking an append only list"
#     
#     * 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity:
#       evm: Fix a small race in init_desc()
#       evm: Fix RCU list related warnings
#       ima: Fix return value of ima_write_policy()
#       evm: Check also if *tfm is an error pointer in init_desc()
#       ima: Set file->f_mode instead of file->f_flags in ima_calc_file_hash()
