Pavel Begunkov 74a37ce697 io_uring: fix waiters missing wake ups ... There are reports of mariadb hangs, which is caused by a missing barrier in the waking code resulting in waiters losing events. The problem was introduced in a backport 3ab9326f93 ("io_uring: wake up optimisations"), and the change restores the barrier present in the original commit 3ab9326f93 ("io_uring: wake up optimisations") Reported by: Xan Charbonnet <xan@charbonnet.com> Fixes: 3ab9326f93 ("io_uring: wake up optimisations") Link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1093243#99 Reviewed-by: Li Zetao <lizetao1@huawei.com> Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2025-02-01 18:30:09 +01:00
