This patch set retrieves the number of LUs available on a target using the report-luns command. The initial size of the report-luns command is 512 entries, as the previous default initial number was. If more LUs than 511 are present on a target, the report-luns is re-issued with the size indicated in the result of the original report-luns, up to max_report_luns.
The default value of max_report_luns is increased to 16k-1 from 512-1. 3rd version changes from 2nd posting: - add a patch to use get/put_unaligned_be32() in report-luns code 2nd version changes from first posting: - Minor tweak added in 2nd patch to use the number of luns reported in the 2nd report-luns command, if it is executed. There is a chance that the number changed between the 1st and 2nd report-luns. - Add 3rd patch changing kmalloc flag in report luns from GFP_ATOMIC to GFP_KERNEL, as this is more consistent with the allocation flag in blk_alloc_queue_node() Rob Evers (4): Encapsulate scsi_do_report_luns Configure reported luns Change kmallocs in report_luns to use GFP_KERNEL Use set/get_unaligned_be32 in report_luns drivers/scsi/scsi_scan.c | 192 +++++++++++++++++++++++++++++------------------ 1 file changed, 120 insertions(+), 72 deletions(-) -- 1.7.11.7 -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
