Its filename is selftests-mm-fix-exit-code-in-pagemap_ioctl.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/selftests-mm-fix-exit-code-in-pagemap_ioctl.patch This patch will later appear in the mm-new branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Note, mm-new is a provisional staging ground for work-in-progress patches, and acceptance into mm-new is a notification for others take notice and to finish up reviews. Please do not hesitate to respond to review feedback and post updated versions to replace or incrementally fixup patches in mm-new. The mm-new branch of mm.git is not included in linux-next Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via various branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there most days ------------------------------------------------------ From: Kevin Brodsky Subject: selftests/mm: fix exit code in pagemap_ioctl Date: Wed, 7 Jan 2026 16:48:41 +0000 Make sure pagemap_ioctl exits with an appropriate value: * If the tests are run, call ksft_finished() to report the right status instead of reporting PASS unconditionally. * Report SKIP if userfaultfd isn't available (in line with other tests) * Report FAIL if we failed to open /proc/self/pagemap, as this file has been added a long time ago and doesn't depend on any CONFIG option (returning -EINVAL from main() is meaningless) Link: https://lkml.kernel.org/r/20260107164842.3289559-8-kevin.brodsky@arm.com Signed-off-by: Kevin Brodsky Reviewed-by: Ryan Roberts Reviewed-by: Mark Brown Acked-by: David Hildenbrand (Red Hat) Cc: Usama Anjum Cc: Jason Gunthorpe Cc: John Hubbard Cc: "Liam R.
