Hi,
I've fixed Alex's v5.
changes v5->v6:
* add test_file parameter to ima_check() (using global for function is ugly)
* keep $TEST_FILE in ima_measurements.sh ]
* add verify_measurement() (DRY)
Alex Henrie (3):
IMA: Move check_policy_writable() to ima_setup.sh and rename it
IMA: Move ima_check to ima_setup.sh
IMA: Add tests for uid, gid, fowner, and fgroup options

yw. FYI I'll merge v7 after it's merged into mainline, I expect it'll be in v5.16-rc1.
Could you please notify me if I forget?
I'll try to have look into kernel patch itself.
Kind regards,
