From 3652117f854819a148ff0fbe4492587d3520b5e5 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Wed, 22 Nov 2023 13:48:23 +0100 Subject: eventfd: simplify eventfd_signal() Ever since the eventfd type was introduced back in 2007 in commit e1ad7468c77d ("signal/timer/event: eventfd core") the eventfd_signal() function only ever passed 1 as a value for @n. There's no point in keeping that additional argument.
