Hello,

kernel test robot noticed "kernel-selftests.seccomp.seccomp_bpf.fail" on:

If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags

we noticed one test added in this commit can pass, but another will fail.

we applied the patch set upon 31c65705a8cfa like below:

95084d9b2b5f0 (linux-review/Hengqi-Chen/seccomp-Introduce-SECCOMP_LOAD_FILTER-operation/20231129-134337) selftests/seccomp: Test seccomp filter load and attach
8fcda1c36e519 seccomp: Introduce new flag SECCOMP_FILTER_FLAG_FILTER_FD
bd86f21cfe1e0 seccomp: Introduce SECCOMP_LOAD_FILTER operation
31c65705a8cfa (kees/for-next/seccomp, kees/for-linus/seccomp) perf/benchmark: fix seccomp_unotify benchmark for 32-bit
ce9ecca0238b1 (tag: v6.6-rc2, hyperv/hyperv-next) Linux 6.6-rc2


not sure if this is the correct base, or is there any other dependency to run
new test seccomp_attach_fd_failed?
