Fix is merged in 5.5-rc6. Could we get it for 5.4 (stable branch)?

that's upstream commit: 46bcff2bfc5e ("btrfs: fix compressed write bio blkcg attribution") and maybe as well: 7b62e66cbbfb ("btrfs: punt all bios created in btrfs_submit_compressed_write()") Wenruo can you take care of this? This issue blocks tumbleweed update on aarch64/arm64. -- You are receiving this mail because: You are on the CC list for the bug.

To reporduce that the cgroups2 and io controler need to be enabled. Also, the stacktraces are different so I don't think it's the same bug. -- You are receiving this mail because: You are on the CC list for the bug.

It would need more tests, but it seems to be better with kernel 5.5.

It still happens with kernel 5.5.11 in current Tumbleweed on ThunderX1 machines in OBS while building aarch64 kiwi images. -- You are receiving this mail because: You are on the CC list for the bug.

I guess Nik has pinned down the root cause, and the upstream fix is here:

https://patchwork.kernel.org/project/linux-btrfs/patch/20211102124916.433836... 1-nborisov@suse.com/

Mind to test if this patch solves the problem?

This patch is in kernel 5.15.5 which is currently tested in staging, and thus, should land in :Factory:ARM in the coming days. -- You are receiving this mail because: You are on the CC list for the bug.
