Some notes:

1. Triggering partial reads/writes requires a rather exotic filesystem (so far we only have reports from configurations involving a distributed or network-based FS).

2. The patch appears to be correct, but addresses a rather uncommon code path for 5.5 and later versions, since it only fixes synchronous IO, whereas on MySQL 5.5 and later asynchronous IO is used by default.

So the problem with AIO calls in PS 5.5 / 5.6 still exists with fixes for both bugs. Therefore, I don't think this bug is related to bug #1177201. Due to above considerations, this bug is also certainly not High importance.

I have reported bug #1263087 to track the AIO part.
