    target/file: Bump FD_MAX_SECTORS to 2048 to handle 1M sized I/Os · f002a243
    Nicholas Bellinger authored
    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.
