Subject: [PATCH for-next v3 6/6] RDMA/rxe: Replace missing rxe_pool_get_index_locked
Date: Mon, 25 Jan 2021 15:16:41 -0600	[thread overview]
Message-ID: <20210125211641.2694-7-rpearson@hpe.com> (raw)
In-Reply-To: <20210125211641.2694-1-rpearson@hpe.com>

[v2]
One of the pool APIs for when caller is holding lock was not defined
but is declared in rxe_pool.h. This patch adds the definition.
