Hello,
we think this commit is not the root cause of the "CFI failure", but it
changes the failure's stats:
f1c09a0b6add651e 34f170a590710737f9611231cd7
---------------- ---------------------------
fail:runs %reproduction fail:runs
| | |
6:6 -100% :6 dmesg.CFI_failure_at_crypto_acomp_alloc_streams
:6 100% 6:6 dmesg.CFI_failure_at_sk_filter_trim_cap
6:6 -100% :6 dmesg.RIP:crypto_acomp_alloc_streams
:6 100% 6:6 dmesg.RIP:sk_filter_trim_cap
for comparision, one parent dmesg is attached.
we don't have enough knowledge how this commit is related with this stats change
and our auto-bisect is broken due to this stats change then we failed to bisect
the fbc for dmesg.CFI_failure_at_crypto_acomp_alloc_streams, so we just make out
below report FYI what we observed in our tests.
kernel test robot noticed "CFI_failure_at_sk_filter_trim_cap" on:
commit: 34f170a590710737f9611231cd77b37ea41f707a ("crypto: simd - Include asm/simd.h in internal/simd.h")

compiler: clang-20

(please refer to attached dmesg/kmsg for entire log/backtrace)
