[PATCH 5.10 CANDIDATE 0/7] xfs stable candidate patches for 5.10.y (part 3)

[Amir Goldstein <amir73il@gmail.com>]

Hi all!

This is the 3rd part of a collection of stable patch candidates that
I collected from xfs releases v5.11..v5.18.

Part #1 is already in 5.10.120 and part #2 has been posted to stable.

The patches in this part are from circa v5.12..v5.13.

They have been soaking in kdevops for over a week with no regressions
from baseline observed.

There are four user visible fixes in this part, one patch for dependency
("rename variable mp") and two patches to improve testability of LTS.

Specifically, I selected the fix ("use current->journal_info for
detecting transaction recursion") after I got a false positive assert
while testing LTS kernel with XFS_DEBUG and at another incident, it
helped me triage a regression that would have been harder to trace
back to the offending code otherwise.

It is worth noting that one patch from v5.13 did cause a regression
and was removed from the stable candidates queue during early testing -
0fe0bbe00a6f ("xfs: bunmapi has unnecessary AG lock ordering issues").

When I did a post mortem on a patch that I missed for part #2, I started
off on the wrong foot with Dave, so it is important for me to say this:
Although I had wrongly selected this fix, all the information I needed
to make the right decision was in the commit message, I just did not
understand it at the time that I selected the patch.

But when my tests had detected hangs on test xfs/299, that quickly lead
me to the mention of xfs/299 in the commit message and then I understood
that the fix was incorrect without "deferred inode inactivation" series
from 5.13-rc1.

I would like to thank Samsung and Luis for the resources and efforts
that make this work possible.

Your inputs on these stable candidates are most welcome!

Thanks,
Amir.
