The quilt patch titled Subject: selftests/mm: enable mrelease_test for arm64 has been removed from the -mm tree. Its filename was selftests-mm-enable-mrelease_test-for-arm64.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Ryan Roberts <ryan.roberts@xxxxxxx> Subject: selftests/mm: enable mrelease_test for arm64 Date: Mon, 24 Jul 2023 09:25:17 +0100 mrelease_test defaults to defining __NR_pidfd_open and __NR_process_mrelease syscall numbers to -1, if they are not defined anywhere else, and the suite would then be marked as skipped as a result. arm64 (at least the stock debian toolchain that I'm using) requires including <sys/syscall.h> to pull in the defines for these syscalls. So let's add this header. With this in place, the test is passing on arm64.
