Thanks for the backport. The 6.12.y version has been queued.

For 6.6.y, the diff isn't a straight cherry-pick and the rewritten
ksmbd_free_global_file_table() path in particular is a non-trivial
stable-only adaptation. Before I queue this for 6.6.y, could you get
Acks from the ksmbd maintainers on the 6.6.y diff specifically? In
particular:

  Namjae Jeon <linkinjeon@kernel.org>
  Steve French <stfrench@microsoft.com>

Once one of them has Ack'd the 6.6 adaptation I'll pick it up.
