Several people reported IO-related issues since kernel 6.1.6 [0].
Things got better with 6.1.10, but apparently the issues are not fully
resolved (e.g. [1]).
I ran into an issue with PBS backup of a VM with passed-through disks
(error with 6.1.6, hang with 6.1.10+) and found that the issue did not
occur anymore with v6.3-rc1. Bisecting what fixed the issue led to the
commit in this patch. The hope is that it fixes some other issues too.
The commit has a CC-stable tag for 5.15+, but telling from the absence
of user reports, it was much less likely to trigger before 6.1.x (it's
not clear what x is, because of the other issue in 6.1.6). The commit
says it depends on 613b14884b85 ("block: handle bio_split_to_limits()
NULL return") which is already present as a3f1c82e0413 ("block:
handle bio_split_to_limits() NULL return") in the Ubuntu tree.
