From 120ae58593630819209a011a3f9c89f73bcc9894 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Wed, 22 Nov 2023 13:48:24 +0100 Subject: eventfd: simplify eventfd_signal_mask() The eventfd_signal_mask() helper was introduced for io_uring and similar to eventfd_signal() it always passed 1 for @n. So don't bother with that argument at all.
