This is a bcachefs bug: it should be using the REQ_PREFLUSH flag instead of
REQ_OP_FLUSH. It's fixed in mainline v6.8-rc2 via 3e44f325f6f75 ("bcachefs: fix
incorrect usage of REQ_OP_FLUSH").

I've submitted the fix for Tumbleweed inclusion via
https://kerncvs.suse.de/gitweb/?p=kernel-source.git;a=shortlog;h=refs/heads/users/ddiss/stable/for-next
