Subject: [PATCH RESEND 2/2] RDMA/mlx5: Fix xlt_chunk_align calculation
Date: Wed, 8 Sep 2021 10:18:49 +0200 [thread overview]
Message-ID: <20210908081849.7948-2-schnelle@linux.ibm.com> (raw)
In-Reply-To: <20210908081849.7948-1-schnelle@linux.ibm.com>
The XLT chunk alignment depends on ent_size not sizeof(ent_size) aka
sizeof(size_t).
Cc: stable@vger.kernel.org
Fixes: 8010d74b9965b ("RDMA/mlx5: Split the WR setup out of mlx5_ib_update_xlt()")
