[0/2] Raid5 Bug Fixes

Message

Logan Gunthorpe July 7, 2022, 7:15 p.m. UTC

Hey,

Please find two patches with fixes to the raid5 code.

The first patch fixes a bug in my recent commit that causes data
corruption in very specific circumstances.

The second patch fixes a theoretical issue with nested waits in
code that was recently cleaned up in the previous series (though the
issue always existed).

Thanks,

Logan

Applied to md-next after fixing a couple typos.
