Hi Martin,
This patch series simplifies and optimizes the UFS driver. Please consider
this patch series for kernel v5.6.
Thanks,
Bart.
Changes compared to v6:
- Reduced this patch series to include only those patches that received
positive reviews.
Changes compared to v5:
- Reworked patch 4/4 such that it only modifies the clock scaling code and
no other code. Added more comments in the code and improved the patch
description.
- Rebased this patch series on top of the 5.5/scsi-queue branch.
Changes compared to v4:
- Reverted back to scsi_block_requests() / scsi_unblock_requests() for the
UFS error handler.
- Added a new patch that serializes error handling and command submission.
- Fixed a blk_mq_init_queue() return value check.
Changes compared to v3:
- Left out "scsi" from the name of the functions that suspend and resume
command processing.
Changes compared to v2:
- Use a separate tag set for TMF tags.
Changes compared to v1:
- Use the block layer tag infrastructure for managing TMF tags.
Bart Van Assche (2):
ufs: Avoid busy-waiting by eliminating tag conflicts
ufs: Use blk_{get,put}_request() to allocate and free TMFs
