[SRU][Focal-OEM-5.14/Jammy-OEM-5.17][PATCH 0/1] CVE-2022-3649

[Yuxuan Luo]

[Impact]
If the disk is already corrupted while the user is using NILFS, there exists
a situation that the file system would erroneously operate and crush.

[Backport]
The patch d325dc6eb763c10f591c239550b8c7e5466a5d09 can be cherry-picked to both
releases.

[Testing]
Compile tested.

[Potential Regression]
This patch does not alter any existing logic but add a handler for a rare
situation; therefore, expecting low risk of regression.
