Subject: [PATCH rdma-rc] RDMA/counter: Query a counter before release
Date: Sun, 21 Jun 2020 14:00:00 +0300 [thread overview]
Message-ID: <20200621110000.56059-1-leon@kernel.org> (raw)
From: Mark Zhang <markz@mellanox.com>
Query a dynamically-allocated counter before release it, to update it's
hwcounters and log all of them into history data. Otherwise all values
of these hwcounters will be lost.
