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.
Not present in linux-image-6.5.0-2
Public bug reported:
While tracking down a lockup while running `lvremove` on a 2TB sized LV with
4.15.0-58.64, I noticed that upgrading to 4.15.0-62.69 makes the operation
succeed, but still print:
```
/dev/mapper/test: BLKDISCARD ioctl at offset 1048576 size 6442450944000 failed:
Operation no
AFAICS e83fa67edfb534976dc4133e634519084153c0e7 got backported before
2.13.2 (8661ebcb7910e03bfcdb6fbf99616120a398d576). And the
apparmor_parser binary has the --compile-features flag in the version in
buster.
I tested with both the versions from buster (2.13.2-10) and sid (2.13.3-4):
apparmor_par
The feature file is the one currently shipped by buster.

Public bug reported:
When setting a features-file in /etc/apparmor/apparmor.conf (and using policies
for this feature-set) certain operations are DENIED, although they should be
allowed.
This occurs for example when running an Ubuntu kernel with Debian Buster
apparmor.
