Subject: [PATCH AUTOSEL 5.4 031/350] IB/iser: bound protection_sg size by data_sg size
Date: Tue, 10 Dec 2019 15:58:43 -0500 [thread overview]
Message-ID: <20191210210402.8367-31-sashal@kernel.org> (raw)
In-Reply-To: <20191210210402.8367-1-sashal@kernel.org>
From: Max Gurtovoy <maxg@mellanox.com>
[ Upstream commit 7718cf03c3ce4b6ebd90107643ccd01c952a1fce ]
In case we don't set the sg_prot_tablesize, the scsi layer assign the
default size (65535 entries). We should limit this size since we should
take into consideration the underlaying device capability. This cap is
considered when calculating the sg_tablesize. Otherwise, for example,
we can get that /sys/block/sdb/queue/max_segments is 128 and
/sys/block/sdb/queue/max_integrity_segments is 65535.
