Re: [PATCH v4 0/3] ceph: don't unregister an MDS session before removing its caps

Hi Max,

Do you have any plans to move this series forward?

Patch 1/3 completes the fix for CVE-2026-89654 (use-after-free
in check_new_map()): the earlier fix ee611a750955 still leaves
the UAF in place. We are tracking this CVE in our
downstream kernels, so we'd really like to see the series land
in mainline. The thread, however, has been quiet since
Sep 8th, when 3/3 picked up Xiubo's Reviewed-by, and the
patches are in neither the ceph-client testing branch nor
mainline yet.

Is there anything still holding the series back that we could
help with?

Thanks,
Chen Yuxi
