Leah, thanks for doing the backport to 5.4! And Greg, thanks for queuing them up.
I note that if we first cherry pick into 4.19.y a fix from 5.2 that probably should have been cc'ed to stable to begin with:
0a944e8a6c66 ("ext4: don't perform block validity checks on the journal inode")
This commit is already in the following releases: 3.16.85 4.4.221 4.4.263 4.9.221 4.9.263 4.14.178 4.14.227 4.19.73 4.19.182 5.2 5.7.18 5.8.4
Leah's three backports to 5.4 will then apply to 4.19 LTS; I've run regression tests with the cherry-pick of 0a944e8a6c66 and Leah's three backports applied to 4.19.230, and the resulting kernel looks fine and prevents a kernel crash when running ext4/054.
Greg, would you prefer that I send the patches for 4.19.y, or do you have what you need to do the cherry pick (all of the cherry picks are clean, and didn't require any manual resolution)?
The second commit does not apply cleanly, so I would need working backported ones to get this right. I have queued up the first one now already.
thanks,
