stable inclusion from stable-v5.10.102 commit 139fce2992ee88528714a56aaee7c45dd1ec7f7a bugzilla: https://gitee.com/openeuler/kernel/issues/I567K6
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit dae1d8ac31896988e7313384c0370176a75e9b45 ]
Report mincore.check_file_mmap as SKIP instead of FAIL if the underlying filesystem lacks support of O_TMPFILE or fallocate since such failures are not really related to mincore functionality.
