Its filename was selftests-mm-fix-hugetlb-pathname-construction-in-hugetlb_reparenting_testsh.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Sayali Patil Subject: selftests/mm: fix hugetlb pathname construction in hugetlb_reparenting_test.sh Date: Thu, 12 Mar 2026 17:55:30 +0530 The hugetlb_reparenting_test.sh script constructs hugetlb cgroup memory interface file names based on the configured huge page size. The script formats the size only in MB units, which causes mismatches on systems using larger huge pages where the kernel exposes normalized units (e.g. "1GB" instead of "1024MB"). As a result, the test fails to locate the corresponding cgroup files when 1GB huge pages are configured. Update the script to detect the huge page size and select the appropriate unit (MB or GB) so that the constructed paths match the kernel's hugetlb controller naming. Also print an explicit "Fail" message when a test failure occurs to improve result visibility.
