[PATCH] xfs: wrong error sign conversion during failed DIO writes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dave Chinner <dchinner@xxxxxxxxxx>

We negate the error value being returned from a generic function
incorrectly. The code path that it is running in returned negative
errors, so there is no need to negate it to get the correct error
signs here.

This was uncovered by generic/019.
