[PATCH 0/2] linux-aio: fix unbalanced plugged counter in laio_io_unplug()

[Stefan Hajnoczi]

An unlucky I/O pattern can result in stalled Linux AIO requests when the
plugged counter becomes unbalanced. See Patch 1 for details.

Patch 2 adds a comment to explain why the laio_io_unplug() even checks max
batch in the first place.
