The patch titled Subject: memfd_secret: use unsigned int rather than long as syscall flags type has been removed from the -mm tree. Its filename was secretmem-test-add-basic-selftest-for-memfd_secret2-fix.patch This patch was dropped because an updated version will be merged ------------------------------------------------------ From: Mike Rapoport <rppt@xxxxxxxxxxxxx> 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.
