linux-azure: Missing ext4 commits

[Tim Gardner]

SRU Justification

[Impact]

Microsoft has a test that checks for missing file system commits; It has detected that these commits are not present in Azure tuned kernels:

0f2f87d51aebcf71a709b52f661d681594c7dffa ext4: prevent partial update of the extent blocks
9c6e071913792d80894cd0be98cc3c4b770e26d3 ext4: check for inconsistent extents between index and leaf block
8dd27fecede55e8a4e67eef2878040ecad0f0d33 ext4: check for out-of-order index extents in ext4_valid_extent_entries()

[Test Case]

Microsoft tested

[Where things could go wrong]

Ext4 file systems could have problems.

Marking Impish invalid since those commits came in via stable updates.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-azure/5.4.0-1071.74 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-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

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.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
