Dylan Reid becca3722d io_uring: handle EBUSY from uring_enter ... enter can fail if there are too many pending ops. This will return EBUSY. The user will have to handle some completions before trying again. Only count sqes as submitted by resetting self.added when enter returns success. The number of sqes must also be guarded if too many are added before the kernel can update the head pointer. TEST=added ebusy unit test Change-Id: I0c20677f1332732aab09f025e110eca0c2a42500 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/2296699 Tested-by: Dylan Reid <dgreid@chromium.org> Commit-Queue: Dylan Reid <dgreid@chromium.org> Reviewed-by: Chirantan Ekbote <chirantan@chromium.org>		2020-07-17 15:06:15 +00:00
