io_uring: pass in EPOLL_URING_WAKE for eventfd signaling and wakeups
stable inclusion from stable-v5.10.162 commit 189556b05e1770263c43fa5b4c689e7cd3fa5b4e category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7P7OH Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=189556b05e1770263c43fa5b4c689e7cd3fa5b4e -------------------------------- [ Upstream commit 44648532 ] Pass in EPOLL_URING_WAKE when signaling eventfd or doing poll related wakups, so that we can check for a circular event dependency between eventfd and epoll. If this flag is set when our wakeup handlers are called, then we know we have a dependency that needs to terminate multishot requests. eventfd and epoll are the only such possible dependencies.
