Hello,

on the latest kernel a fio job with 4 workers using libaio hangs.

git bisect points to:
	commit e02ba72aabfade4c9cd6e3263e9b57bf890ad25c
	Author: Anatol Pomozov <anatol.pomozov@gmail.com>
	Date:   Tue Apr 15 11:31:33 2014 -0700

	    aio: block io_destroy() until all context requests are completed


The fio workers are on the wait_for_completion in sys_io_destroy.

Regards,
Sebastian
