Thomas Schoebel-Theuer	81ca278291	aio: fix race on file size ... The old code used mf->mf_max for correcting the file size, but that was wrong for multiple writes in flight. A really correct solution would have to remember all in-flight writes and compute their minimum IO position. Since that would be too costly, we just use the old size before any writes have started. This might be too conservative for extremely high load patterns (possible starvation problem). For now, take this and check whether we really need higher effort.	2013-06-20 15:08:28 +02:00
