From: Chen, Kenneth W Date: Tue, 12 Jul 2005 22:57:13 +0000 (-0700) Subject: [SCSI] Redundant this_count check in sd_init_command() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7fce2cf62e4bd9c24717009865ac00940cb664b8;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [SCSI] Redundant this_count check in sd_init_command() I was going over the scsi I/O submit path, when sd_init_command construct the scsi command, this_count is already checked in the previous else if clause. Why does it need to check it again in the last else block? Patch to delete the spurious check.
