Subject: [drm/i915]  be7612fd66: invoked_oom-killer:gfp_mask=0x



Greeting,

FYI, we noticed the following commit (built with gcc-9):

commit: be7612fd6665f5ef3f6c89e78bb4ec4dbff6cd16 ("drm/i915: Require object lock when freeing pages during destruction")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: igt
version: igt-x86_64-60e5ffca-1_20220309
with following parameters:

	group: gem_ctx_exec
	ucode: 0xec



on test machine: 4 threads Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz with 32G memory

caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):


(please be noted we notice there is a fix commit:
[6cb12fbda1c2e2fcb6d3adfe01f18eef6812e278] drm/i915: Use trylock instead of blocking lock for __i915_gem_free_objects.
but in our tests, the issue still exists on it, as well as on latest mainline
and linux-next/master, upon our test platform as above)


If you fix the issue, kindly add following tag

        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.
