3.6.11.2 stable review patch. If anyone has any objections, please let me know. ------------------ From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx> [ Upstream commit f002a24388cc460c8a9be7d446a9871f7c9d52b6 ] This patch bumps the default FILEIO backend FD_MAX_SECTORS value from 1024 -> 2048 in order to allow block_size=512 to handle 1M sized I/Os. The current default rejects I/Os larger than 512K in sbc_parse_cdb(): [12015.915146] SCSI OP 2ah with too big sectors 1347 exceeds backend hw_max_sectors: 1024 [12015.977744] SCSI OP 2ah with too big sectors 2048 exceeds backend hw_max_sectors: 1024 This issue is present in >= v3.5 based kernels, introduced after the removal of se_task logic.
