Hi-

The Fixes: tag seems incorrect to me.

86c4ccd9b92b correctly makes xprt_rdma_slot_table_entries a
global variable. This later commit (in v5.6-rc1)

7581d90109ca ("xprtrdma: Refactor initialization of ep->rep_max_requests")

should have changed xprt_rdma_slot_table_entries back to a static.

I'm not sure what the call is on sparse warnings these days, but
it doesn't seem like this clean up should be backported to stable. 
Should Fixes: be removed?
