Sasha, you merged my last set of XFS fixes. I asked for one patch to not be merged yet as one issue was not yet properly fixed. After some further review I have identified commits which do fix the kernel crash reported on kz#204223 [0] with generic/388, this patch set applies on top of the last one I sent you. These commits do quite a bit of code refactoring, and the actual fix lies hidden in the last commit by Darrick. Due to the amount of changes trying to extract the fix is riskier than just carring the code refactoring. If we're OK with the code refactor for stable, its my recommendation we keep the changes to match more with upstream and benefit from other fixes. The code refactoring was merged on v4.20 and Darrick's fix is the only fix upstream since the code was merged. If others disagree with this approach please speak up. I've run a full set of fstests against the following sections 12 times and have found no regressions against the baseline: xfs xfs_logdev xfs_nocrc_512 xfs_nocrc xfs_realtimedev xfs_reflink_1024 xfs_reflink_dev Review from others is appreciated.
