6.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Or Har-Toov <ohartoov@xxxxxxxxxx>
[ Upstream commit 0611a8e8b475fc5230b9a24d29c8397aaab20b63 ]
As some mkeys can't be modified with UMR due to some UMR limitations,
like the size of translation that can be updated, not all user mkeys can
be cached.
Fixes: dd1b913fb0d0 ("RDMA/mlx5: Cache all user cacheable mkeys on dereg MR flow")
