Hello,
I noticed yesterday that LTP test preadv03 now fails since 6.1.64 (it also
fails on 6.1.65).
6.6.4, 6.6.3, 6.5.0 and 6.2.0 seem to be unaffected.
I tested this on x86_64 and kvx arch (the latter is not upstream).
I can see some ext4 related commits on 6.1.64 and 6.1.65 changes, maybe it's
related, therefore I add ext4 mailing list as CC.
I didn't run git bisect on this so far because I noticed building an x86_64
ubuntu kernel on my laptop was taking ages. Maybe someone is more used to
dealing with this and can bisect this way faster than me.
Should be fixed in the latest 6.1.y-rc release, right? If not, please
let me know.
Thanks for the quick reply, indeed it seems way better on 6.1.66-rc2.
I tested on kvx arch, all preadv* LTP tests are passing:

The errors during mkfs are weird but maybe it's an issue in kvx port...
at least the test is passing now.
Thanks!
