fanotify: add do_fanotify_mark() helper; remove in-kernel call to syscall
Using the fs-internal do_fanotify_mark() helper allows us to get rid of the fs-internal call to the sys_fanotify_mark() syscall. This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined. For details, see http://lkml.kernel.org/r/20180325162527.GA17492@light.dominikbrodowski.net Acked-by: Jan Kara <jack@suse.cz> Cc: Amir Goldstein <amir73il@gmail.com> Cc: linux-fsdevel@vger.kernel.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
