This bug is awaiting verification that the 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- eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.
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.

The path however is never used anywhere so the struct shiftfs_file_info and therefore the whole kmem cache can go away. This removes code and makes the whole logic simpler to understand and reason about. Fix: Remove the kmem cache for struct shiftfs_file_info and struct shiftfs_file_info itself and move to the same model as overlayfs and just stash away the struct file for the underlay in file->private_data of the shiftfs struct file Regression Potential: Limited to shiftfs. The basic logic is unchanged. It is just simplified so regression potential should be fairly low. Test Case: Tested with LXD on a kernel with the patch applied and running various standard workloads without any observable regressions. Target Kernels: All LTS kernels with support for shiftfs.
