Subject: bug with fastpoll accept and sqpoll + IOSQE_FIXED_FILE
Date: Tue, 2 Feb 2021 00:36:57 -0500	[thread overview]
Message-ID: <CAM1kxwhCXpTCRjZ5tc_TPADTK3EFeWHD369wr8WV4nH8+M_thg@mail.gmail.com> (raw)

started experimenting with sqpoll and my fastpoll accepts started
failing. was banging my head against the wall for a few hours... wrote
this test case below....

basically fastpoll accept only works without sqpoll, and without
adding IOSQE_FIXED_FILE to the sqe. fails with both, fails with
either. these must be bugs?

I'm running Clear Linux 5.10.10-1017.native.

i hope no one here is allergic to C++, haha. compilation command
commented in the gist, just replace the two paths. and I can fold
these checks if needed into a liburing PR later.
