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
