From 4f98f380f4662829e394c840062ea677956b57ec Mon Sep 17 00:00:00 2001 From: Joe Damato Date: Wed, 7 Aug 2024 10:52:31 +0000 Subject: [PATCH] eventpoll: Don't re-zero eventpoll fields Remove redundant and unnecessary code. ep_alloc uses kzalloc to create struct eventpoll, so there is no need to set fields to defaults of 0. This was accidentally introduced in commit 85455c795c07 ("eventpoll: support busy poll per epoll instance") and expanded on in follow-up commits.
