Sure.
We are running LTP Version: 20230516 for our testing.

We will update the latest LTP release (20230929) next week.

> FYI the best LTP release is always the latest release or git master branch.

We have two threads here.
1) LTP release tag testing on all stable-rc branches
2) LTP master testing on a given specific kernel version [a]

Great, this makes sense.

BTW from looking in the log [b] ("INFO: ltp-pan reported some tests FAIL")
I see you use runltp. We recommend to switch to kirk [c]. And we definitely
appreciate your feedback from it.

Kind regards,

Bisection led to "NFS: Fix O_DIRECT locking issues" (upstream commit
7c6339322ce0c6128acbe36aacc1eeb986dd7bf1). Reverting that patch and
"NFS: Fix error handling for O_DIRECT write scheduling" (upstream
commit 954998b60caa8f2a3bf3abe490de6f08d283687a) (not a clean revert
this one) made ltp-dio pass again.

So this is also an issue in Linus's tree?  Or is it only on the 6.1.y
tree.
