Subject: selftests: skip mincore.check_file_mmap when fs lacks needed support
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bced176da6e03c7b7f087d524293dedc7b351ae1;p=linux.git

selftests: skip mincore.check_file_mmap when fs lacks needed support

[ 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.
