From: Madhuranath Iyengar Date: Tue, 4 May 2010 22:01:28 +0000 (-0700) Subject: [SCSI] qla2xxx: Provide common framework for BSG and IOCB commands. X-Git-Tag: firefly_0821_release~9833^2~2084^2^2~21 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=4916392b56921b4aaaeaca3ef492135f42fbb5f2;p=firefly-linux-kernel-4.4.55.git [SCSI] qla2xxx: Provide common framework for BSG and IOCB commands. Currently, BSG and IOCB/Logio commands have a different framework (srb structs). The purpose of this effort is to consolidate them into a generalized framework for these as well as other asynchronous operations in the future.
