Hi,
I just rebased and tweaked these 4 patches ontop of v5.12-rc7.
Been carrying an older ~5.9 based version in RHEL8 (since RHEL8.3,
August 2020; yes the patchset I just mistakenly emailed instead of
this patchset):
https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=nvme-error-handling-fixes/for-5.9
RHEL9 is coming, would really prefer that these changes land upstream
rather than carry them within RHEL.
All review/feedback welcome.
Thanks,
Mike
