From e73823f7a2c921dcf068d34ea03bd682498d9e42 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Tue, 7 May 2013 15:38:18 -0700 Subject: [SCSI] libsas: implement > 16 byte CDB support Remove the arbitrary expectation in libsas that all SCSI commands are 16 bytes or less. Instead do all copies via cmd->cmd_len (and use a pointer to this in the libsas task instead of a copy). Note that this still doesn't enable > 16 byte CDB support in the underlying drivers because their internal format has to be fixed and the wire format of > 16 byte CDBs according to the SAS spec is different. the libsas drivers (isci, aic94xx, mvsas and pm8xxx are all updated for this change.
