I'm sorry but this is really inconsistent information.
The kernel version points to 5.15.159. The commit referenced right after
is for v6.9 though and it goes on...
> freeze_go_sync+0x1d6/0x320 fs/gfs2/glops.c:584
That function doesn't exist on v6.9 and has been removed in
commit b77b4a4815a9 ("gfs2: Rework freeze / thaw logic") which fixes the
deadlock you supposedly detected. So, this must be from a kernel prior
to v6.5.
In general we will ignore bug reports from automated tools that are not
the official syzkaller instance because stuff like this is stealing time
spent actually writing code or fixing bugs.
