Azure: Jammy azure CIFS backport to 5.15-backport-1-24-24 causes regression

[Tim Gardner]

SRU Justification

[Impact]

The backport of git://git.samba.org/sfrench/cifs-2.6.git 5.15-backport-1-24-24 (CIFS) has caused some regressions. See LP: #2064514

[Fix]

Revert backport and restore CIFS to 5.15-backport-8-16-23

[Regression Potential]

Reverting this backport restores CIFS code to that of linux-azure 5.15.0-1064.73 which has passed regression testing.

This bug is awaiting verification that the linux-azure/5.15.0-1066.75 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux-azure' to 'verification-done-jammy-linux-azure'. If the problem still exists, change the tag 'verification-needed-jammy-linux-azure' to 'verification-failed-jammy-linux-azure'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
