Dear friends,

I've rechecked different kernels and this is full summary:

============================

* jammy/linux
- hwe-5.17
* kinetic/linux
- master-next

these branches has no aufs, so we need to port one aufs patch + one fix patch.
I've already sent that as a series:
[SRU][J][hwe-5.17][PATCH 0/2] UBUNTU: SAUCE: overlayfs: fix incorrect mnt_id of files opened from map_files

will resent with clear branches indication

============================

* jammy/linux
- master / master-next

aufs is present, all that we need to remove excess IS_ENABLED(CONFIG_AUFS_FS) check
in fs/overlayfs/file.c. I've sent this change as:
[SRU][J][master-next][PATCH] UBUNTU: SAUCE: overlayfs: remove CONFIG_AUFS_FS dependency

============================

* kinetic/linux
- master
* focal/linux
hwe-5.15-next
hwe-5.13-next

aufs is present, but we have no fix commit here at all. Will send.

============================

Alex
