charset="utf-8" There is no need for aio_context_use_g_source() now that epoll(7) and io_uring(7) file descriptor monitoring works with the glib event loop. AioContext doesn't need to be notified that GSource is being used. On hosts with io_uring support this now enables fdmon-io_uring.c by default, replacing fdmon-poll.c and fdmon-epoll.c. In other words, the event loop will use io_uring!
