We recently had to fix an -rt aufs build failure in linux-yocto 3f9f162d9bb0
("aufs: i_op: Add handling for au_pin_hdir_set_owner with RT kernel") and then
I also recently saw a build fail on allyesconfig for a missing sync_inode().
This got me looking at what we integrated vs. what is currently upstream.
At the time Yocto started with v5.15, the then-current aufs was 5.14-20210906.
Since then, v5.15 specific branches have been created, and issue fixes
covering both the above have been added to aufs5-standalone upstream.
Given that, it seemed that an update to the latest v5.15 content was the
sensible thing to do. This update takes us to the latest on aufs5.15.5
branch, which is 5.15.5-20220221 + two aditional fixes.
One will see below that a significant portion of the updates are related to
fs_context - see https://lwn.net/Articles/780267/ -- while I was originally
on the fence as to whether to include these, the deciding factor was seeing
that they originated on the aufs v5.14 branch before going to aufs v5.15.
So they aren't "new" in that respect.
The aufs5-standalone repository uses git and patches and merges in what could
be described as somewhat non-conventional. Without going into details, it
doesn't lend itself to ease of updates to our previous integration as we
might be used to getting from other more conventional upstream feeds.
As such, what will be seen below is a mix of commits that were relatively
easy to extract, and version bump updates authored by myself that are a
reflection of the mix of files and patches in aufs5-standalone at the
point in time where the version bump 1st appeared. Also one revert of our
early "make v5.14 aufs build on v5.15 baseline" was done to ease layering on
the upstream v5.15 updates (which contained the same/similar build fixes).
To be clear, I've not used aufs before, and so this is a mechanical update
performed after unwinding what we had, in conjunction with how the upstream
moves forward -- followed with allyes/mod/def config build testing.
Testing was on a v5.15.30 standard/base (linux-yocto 70cf8dde5544). And if
users have issues, we should be in a better position to get them resolved by
aligning to the latest.
I can push to linux-yocto-contrib once the push hook is fixed if needed.
Paul.
