Subject: [PATCH AUTOSEL 5.15 17/41] scsi: ibmvscsis: Increase INITIAL_SRP_LIMIT to 1024
Date: Mon, 11 Apr 2022 20:46:29 -0400	[thread overview]
Message-ID: <20220412004656.350101-17-sashal@kernel.org> (raw)
In-Reply-To: <20220412004656.350101-1-sashal@kernel.org>

From: Tyrel Datwyler <tyreld@linux.ibm.com>

[ Upstream commit 0bade8e53279157c7cc9dd95d573b7e82223d78a ]

The adapter request_limit is hardcoded to be INITIAL_SRP_LIMIT which is
currently an arbitrary value of 800. Increase this value to 1024 which
better matches the characteristics of the typical IBMi Initiator that
supports 32 LUNs and a queue depth of 32.

This change also has the secondary benefit of being a power of two as
required by the kfifo API. Since, Commit ab9bb6318b09 ("Partially revert
"kfifo: fix kfifo_alloc() and kfifo_init()"") the size of IU pool for each
target has been rounded down to 512 when attempting to kfifo_init() those
pools with the current request_limit size of 800.
