This bug is awaiting verification that the linux-azure/5.15.0-1083.92 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. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Fix] Backported to the J:azure tree. [Test plan] Build tested only; Microsoft will test the bug fix. [Where problems could occur] Due to the significant delta between the Jammy 5.15 tree and commit 7e043a80b5da, particularly w.r.t. fs/netfs/read_helper.c, that got split into multiple files in 5.17, as well as the change that introduced the usage of folios in netfslib, a manual backported was required. The changes, however, were relatively simple/self-contained, and as such this presents a medium regression risk. Any issues with this patch could manifest as either a null pointer dereference in netfs_rreq_unlock/netfs_rreq_unmark_after_write, or potentially as a hung thread when doing a lot of I/O on an netfs filesystem.
