[PATCH 1/7] cxlflash: query write_zeroes limit for zeroing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The write_same and write_zeroes limits for SCSI are effectively the
same, so the current code works just fine.  But we plan to remove
REQ_OP_WRITE_SAME support, so switch to quering the write zeroes
limit for a zeroing WRITE SAME operation.
