Hi all,
following bug is trying to workaround an error on ppc64le, where zram01.sh LTP test (there is also kernel selftest tools/testing/selftests/zram/zram01.sh, but LTP test got further updates) has often mem_used_total 0 although zram is already filled.
Hi, Petr,
Is it happening on only ppc64le?
I haven't seen it on other archs (x86_64, aarch64).
Is it a new regression? What kernel version did you use?
Found on openSUSE kernel, which uses stable kernel releases 6.0.x. It's probably much older, first I've seen it some years ago (I'm not able to find kernel version), but it was random. Now it's much more common.
Test runs on VM (I can give qemu command or whatever you need to know about it) I'll try to verify it on some bare metal ppc64le.
Hi Petr and Martin,
Thanks for testing and meaning information.
Could you tell how I could create VM to run ppc64le and run the test? I'd like to reproduce in my local to debug it.
Thanks!
