Subject: [PATCH v5 for-next 2/8] RDMA/rxe: Reverse the sense of RXE_POOL_NO_ALLOC
Date: Thu, 2 Dec 2021 17:20:29 -0600 [thread overview]
Message-ID: <20211202232035.62299-3-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20211202232035.62299-1-rpearsonhpe@gmail.com>
Since most rxe objects are now allocated in rdma-core change the
sense of RXE_POOL_NO_ALLOC to RXE_POOL_ALLOC. This makes the code
easier to understand.
