Hi Muhammad, Afraid this patch is causing a regression on our CI system when it turned up in linux-next today. Additionally, 2 of thetests you have added are failing because the scripts are not exported correctly... On 16/01/2024 09:06, Muhammad Usama Anjum wrote: > Add missing tests to run_vmtests.sh.

You will need to add them to the TEST_FILES variable in the Makefile. > +CATEGORY="hugetlb" run_test ./hugetlb-read-hwpoison The addition of this test causes 2 later tests to fail with ENOMEM. I suspect its a side-effect of marking the hugetlbs as hwpoisoned? (just a guess based on the test name!). Once a page is marked poisoned, is there a way to un-poison it? If not, I suspect that's why it wasn't part of the standard test script in the first place. These are the tests that start failing: # # ------------------------------------ # # running ./uffd-stress hugetlb 128 32 # # ------------------------------------ # # nr_pages: 64, nr_pages_per_cpu: 8 # # ERROR: context init failed (errno=12, @uffd-stress.c:254) # # [FAIL] # not ok 18 uffd-stress hugetlb 128 32 # exit=1 # # -------------------------------------------- # # running ./uffd-stress hugetlb-private 128 32 # # -------------------------------------------- # # nr_pages: 64, nr_pages_per_cpu: 8 # # bounces: 31, mode: rnd racing ver poll, ERROR: UFFDIO_COPY error: -12ERROR: UFFDIO_COPY error: -12 (errno=12, @uffd-common.c:614) # # (errno=12, @uffd-common.c:614) # # [FAIL] Quickest way to repo is: $ sudo ./run_vmtests.sh -t "userfaultfd hugetlb" Thanks, Ryan > > nr_hugepages_tmp=$(cat /proc/sys/vm/nr_hugepages) > # For this test, we need one and just one huge page
