------------------ limit Content-Length: 1118 Lines: 33 From: "Martin K. Petersen" <[email protected]> commit 5f4e206666f834340b69ddb43f86de3851c8675a upstream. Previously we used Maximum Unmap LBA Count in the Block Limits VPD to signal the maximum number of sectors we could handle in a single Write Same command. Starting with SBC3r26 the Block Limits VPD has an explicit limit on the number of blocks in a Write Same. This means we can stop abusing a field related to the Unmap command and let our SAT use the proper value in the VPD (Maximum Write Same Length). Signed-off-by: Martin K.
