Subject: [PATCH rdma-rc] tools/testing/scatterlist: Fix overflow of max segment size
Date: Mon, 25 Jan 2021 14:05:27 +0200 [thread overview]
Message-ID: <20210125120527.836363-1-leon@kernel.org> (raw)
From: Maor Gottlieb <maorg@nvidia.com>
Because SCATTERLIST_MAX_SEGMENT was removed and replaced with UINT_MAX,
the test overflows the max_sgement variable. Remove this case.
Fixes: 7a60c2dd0f57 ("drm: Remove SCATTERLIST_MAX_SEGMENT")
