Jonathan, There is a new user for cfmw_list now https://lore.kernel.org/qemu-devel/20240704093404.1848132-1-zhao1.liu@linux.intel.com/ So I think we should drop this patch.

Hi Zhijian, I'm not a "real" user and that bug was originally found by code reading. So that fix won't block your drop. :-) And I think the fix is worth being laned before cfmw_list gets dropped, for being able to port backwards to stable QEMU. > On 02/07/2024 22:34, Jonathan Cameron wrote: > > From: Li Zhijian <lizhijian@fujitsu.com> > > > > There is no user for this member.
