From scsi_init_command(), a function called by scsi_mq_prep_fn(): /* zero out the cmd, except for the embedded scsi_request */ memset((char *)cmd + sizeof(cmd->req), 0, sizeof(*cmd) - sizeof(cmd->req) + dev->host->hostt->cmd_size); In other words, scsi_mq_prep_fn() clears scsi_cmnd.flags. Hence move the clear_bit() call into the else branch, the only branch in which this code is necessary. See also commit f1342709 ("scsi: Do not rely on blk-mq for double completions").

Avoid open coding the checks for the supported logical block sizes and use a mask to check for misaligned I/O. Use our helper functions to scale lba and block count. Reviewed-by:

Martin K. Petersen authored
We have had several bugs due mixing sector and logical block size terminology. In the block layer, a sector is a 512-byte unit regardless of the logical block size of the underlying device. But the term "sector" is still widely used in sd.c when referring to logical block sized units. We previously introduced helper functions such as sectors_to_logical() and logical_to_sectors() to make the distinction clear. Use these to make the code in sd.c consistent wrt. logical blocks and block layer sectors. Use "lba" to describe a logical block address and "nr_blocks" when counting logical blocks. SBC uses "TRANSFER LENGTH" to describe the latter but this term was avoided to prevent confusion with the very similar DMA transfer size (->transfersize) which is counted in bytes. Reviewed-by:

CONFIG_SCSI_UFS_QCOM selects CONFIG_PHY_QCOM_UFS, assuming that this was the only possible PHY driver Qualcomm's UFS controller would use. But in SDM845, the UFS driver is bundled into phy-qcom-qmp, and phy-qcom-ufs is unused. Remove the select, since for SDM845 it adds useless drivers to the build. Signed-off-by:

Currently libsas does not support checking if this condition occurs, nor rectifying when it does. Such a condition is not at all common, however it has been seen on some pre-silicon environments where the initiator PHY only supports a 1.5 Gbit maximum linkrate, mated with 12G expander PHYs and 3/6G SATA phy. This patch adds support for checking and rectifying this condition during initial device discovery only. We do support checking min pathway connection rate during revalidation phase, when new devices can be detected in the topology. However we do not support in the case of the the user reprogramming PHY linkrates, such that min pathway condition is not met/maintained. A note on root port PHY rates: The libsas root port PHY rates calculation is broken. Libsas sets the rates (min, max, and current linkrate) of a root port to the same linkrate of the first PHY member of that same port. In doing so, it assumes that all other PHYs which subsequently join the port to have the same negotiated linkrate, when they could actually be different. In practice this doesn't happen, as initiator and expander PHYs are normally initialised with consistent min/max linkrates. This has not caused an issue so far, so leave alone for now. Tested-by:

Currently the SMP PHY control execution result is checked, however the function result for the command is not. As such, we may be missing all potential errors, like SMP FUNCTION FAILED, INVALID REQUEST FRAME LENGTH, etc., meaning the PHY control request has failed. In some scenarios we need to ensure the function result is accepted, so add a check for this. Tested-by:

Currently much indentation in this file is done with whitespaces instead of tabs, which can make reading difficult, so fix this up. Some other little minor tidy-up is done, but this file still has many other checkpatch warnings (generally linelength > 80 or function arguments have no identifier names). All libsas code can be audited for checkpatch issues later. Signed-off-by:

When SGE buffer containing DIF information crosses 4G boundary, it results in DMA error. This patch fixes this issue by calculating SGE buffer size and if it crosses 4G boundary, driver will split it into multiple SGE buffers to avoid DMA error. Signed-off-by:
