Manoj Kumar	471a5a60aa	cxlflash: Fix read capacity timeout ... The timeout value for read capacity is too small. Certain devices may take longer to respond and thus the command may prematurely timeout. Additionally the literal used for the timeout is stale. Update the timeout to 30 seconds (matches the value used in sd.c) and rework the timeout literal to a more appropriate description. Signed-off-by: Matthew R.

Manoj Kumar	3ebf203093	cxlflash: Replace magic numbers with literals ... Magic numbers are not meaningful and can create confusion. As a remedy, replace them with descriptive literals. Replace 512 with literal MAX_SECTOR_UNIT. Replace 5 with literal CMD_RETRIES. Signed-off-by: Matthew R. Ochs <mrochs@linux.vnet.ibm.com> Signed-off-by: Manoj N.

Matthew R. Ochs	2cb79266d6	cxlflash: Virtual LUN support ... Add support for physical LUN segmentation (virtual LUNs) to device driver supporting the IBM CXL Flash adapter. This patch allows user space applications to virtually segment a physical LUN into N virtual LUNs, taking advantage of the translation features provided by this adapter. Signed-off-by: Matthew R.
