null_blk: fix spurious IO errors after failed past-wp access [ Upstream commit ff77042296d0a54535ddf74412c5ae92cb4ec76a ] Steps to reproduce: BLKRESETZONE zone 0 // force EIO pwrite(fd, buf, 4096, 4096); [issue more IO including zone ioctls] It will start failing randomly including IO to unrelated zones because of ->error "reuse". Trigger can be partition detection as well if test is not run immediately which is even more entertaining. The fix is of course to clear ->error where necessary.
