SRU Justification

Impact:

Microsoft has requested that the 5.15 backport from the upstream 
maintainer (Steve French) be included in Jammy linux-azure. These 
patches upgrade CIFS to the same level as Linux v6.8.

git://git.samba.org/sfrench/cifs-2.6.git 5.15-backport-1-24-24

Test Plan:

Microsoft tested.

Regression Potential:

Regressions could include failure to connect, DNS resolution failures, 
dropped connections, etc. However, Microsoft has tested these patches 
extensively since January 2024.

SF: #00383839
