Its filename is secretmem-test-add-basic-selftest-for-memfd_secret2-fix.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/secretmem-test-add-basic-selftest-for-memfd_secret2-fix.patch and later at https://ozlabs.org/~akpm/mmotm/broken-out/secretmem-test-add-basic-selftest-for-memfd_secret2-fix.patch 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 and is updated there every 3-4 working days ------------------------------------------------------ From: Mike Rapoport Subject: memfd_secret: use unsigned int rather than long as syscall flags type Yuri Norov says: If parameter size is the same for native and compat ABIs, we may wire a syscall made by compat client to native handler. This is true for unsigned int, but not true for unsigned long or pointer. That's why I suggest using unsigned int and so avoid creating compat entry point. Use unsigned int as the type of the flags parameter in memfd_secret() system call.
