Signed-off-by: Mickaël Salaün Reviewed-by: Thibaut Sautereau Cc: Al Viro Cc: Andrew Morton Cc: Arnd Bergmann Cc: Kees Cook Cc: Vincent Strubel --- Changes since v9: * Rename introspect_access(2) to trusted_for(2). * Increase syscall number to leave space for memfd_secret(2) in -next. Changes since v7: * New patch for the new syscall. * Increase syscall numbers by 2 to leave space for new ones (in linux-next): watch_mount(2) and process_madvise(2). ---
