From: Sreekanth Reddy Date: Mon, 12 Jan 2015 06:09:00 +0000 (+0530) Subject: mpt2sas, mpt3sas: fix upper bound for the module parameter max_sgl_entries X-Git-Tag: fixes-v4.0-rc1~143^2~69 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ad666a0f41d98e4420acdbfd0e5f25e10f768e13;p=pandora-kernel.git mpt2sas, mpt3sas: fix upper bound for the module parameter max_sgl_entries Change Set: 1. Extended the upper boundary restriction for the module parameter max_sgl_entries. Earlier, the max_sgl_entries was capped at the SCSI_MAX_SG_SEGMENTS kernel definition. With this change, the user would be able to set the max_sgl_entries to any value which is greater than SCSI_MAX_SG_SEGMENTS and less than the minimum of SCSI_MAX_SG_CHAIN_SEGMENTS & hardware limit (Calculated using IOCFacts's MaxChainDepth). 2. Added a print for the message log whenever the user sets the max_sgl_entries to a value greater than SCSI_MAX_SG_SEGMENTS to warn about the kernel definition overriding.
