Chuck Lever 83e025da9f xprtrdma: Fix rpcrdma_reqs_reset() ... [ Upstream commit acd9f2dd23 ] Avoid FastReg operations getting MW_BIND_ERR after a reconnect. rpcrdma_reqs_reset() is called on transport tear-down to get each rpcrdma_req back into a clean state. MRs on req->rl_registered are waiting for a FastReg, are already registered, or are waiting for invalidation. If the transport is being torn down when reqs_reset() is called, the matching LocalInv might never be posted. That leaves these MR registered /and/ on req->rl_free_mrs, where they can be re-used for the next connection. Since xprtrdma does not keep specific track of the MR state, it's not possible to know what state these MRs are in, so the only safe thing to do is release them immediately.
