Bug Description
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The following upstream
stable patches should be included in the Ubuntu kernel:
upstream stable patchset 2024-02-27
from git://git.
Revert "nfsd: call nfsd_last_thread() before final nfsd_put()"
cifs: fix flushing folio regression for 6.1 backport
UBUNTU: Upstream stable to v6.1.73, v6.6.12

this change seems to break copying files within a CIFS mount (cp is getting killed, and dmesg contains a BUG entry pointing to cifs_flush_folio - see the attached dmesg.log).
Reproduced with 2 different Samba-shares with the current 6.5.0-32-generic linux-image. 6.5.0-26- generic

Reverting "cifs: fix flushing folio regression for 6.1 backport" makes the issue disappear in my tests. ef40dd17bf62c04 2be8f6d4a4b` probably introduced the change in 6.4, and is part of the mantic source, while it is not in the 6.1 tree)
(Which seems sensible, since, at a very quick glance, `66dabbb65d673a
