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.

so that plain Debian crda + wireless-regdb can work, alternatively we
could disable CRDA and bake in the regdb directly in the kernel,
using the CFG80211_INTERNAL_REGDB KConfig.

but allow discarding BTF information when loading modules, so that upgrades
which are otherwise ABI compatible still work. this allows using BTF
information when matching and available, while degrading gracefully if the
currently running kernel is not identical to the one that module was built for.
in case of a mismatch, the kernel will log a warning when loading the module,
for example:
Jan 30 13:57:58 test kernel: BPF: type_id=184 bits_offset=4096
Jan 30 13:57:58 test kernel: BPF:
Jan 30 13:57:58 test kernel: BPF: Invalid name
Jan 30 13:57:58 test kernel: BPF:
Jan 30 13:57:58 test kernel: failed to validate module [bonding] BTF: -22

The following issue reported on the community forum [0] is likely
fixed by this.
In my case, loading a VM snapshot that originally was taken on an
Intel CPU on my AMD-based host often caused problems in other VMs. In
particular, it often led to CPU stalls, and sometimes clock jumps far
into the future. With this backport applied, everything seems to run
smoothly even after loading the "bad" snapshot 10 times.
The backport from upstream commit 11d39e8cc43e ("KVM: SVM: fix tsc
scaling cache logic consisted of dropping the parts for nested TSC
scaling, which is not yet present in our kernel, renaming the constant
for the default ratio, and some context changes.
