Tomo, List
Please find a patch that updates the BLOCK_LIMITS page.
It specifies that the COMPARE_AND_WRITE command is supported and the limit is 126 blocks.
If thin provisioning is active for the LUN it also sets MAXIMUM UNMAP LBA COUNT and BLOCK DESCRIPTOR COUNT to -1 to indicate that UNMAP is supported and that tere is no limit on how many LBAs or descriptors can be specified.
regards
ronnie sahlberg
