| H A D | poll.c | 44648532 Sun Nov 20 11:18:45 CST 2022 Jens Axboe <axboe@kernel.dk> io_uring: pass in EPOLL_URING_WAKE for eventfd signaling and wakeups
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.
