Stops short of actually using DM's various logging macros (e.g. DMERR, DMINFO, etc) because VDO's logger isn't quite compatible with them. Also switch emit_log_message_to_kernel() from open-coding printk with log-level to using corresponding pr_ macro. Signed-off-by:

Prepare to bring VDO's logging closer to DM's logging by eliminating support for KERN_NOTICE log level (DM hasn't ever had a need for it). Only one message in index-session.c used UDS_LOG_NOTICE, convert it to log with uds_log_info(). Signed-off-by:

Use /* ... */ rather than /** ... */ if for no other reason than syntax highlighting is improved (at least for me, in emacs: comments are now red, code is yellow. Previously comments were also yellow). Signed-off-by:

Add a __must_hold sparse annotation to launch_dedupe_state_change that reflects its ASSERTION code comments about locking requirements, add some extra braces and fix a couple typos. Signed-off-by:

Only one user of WRITE_FLAGS so no need to factor it out in an enum (which causes sparse's 'mixed bitwiseness' warning). Just use the flags in the only consumer. Signed-off-by:

Annotate both open_index() and close_index() with __must_hold(&zones->lock) to silence these sparse warnings: warning: context imbalance in 'close_index' - unexpected unlock warning: context imbalance in 'open_index' - unexpected unlock Signed-off-by:

Factor wait_permit() out from acquire_permit() so that the latter always holds the spinlock and the former always releases it. Otherwise sparse complains about locking context imbalances due to conditional spin_unlock in acquire_permit: warning: context imbalance in 'acquire_permit' - different lock contexts for basic block warning: context imbalance in 'vdo_launch_bio' - unexpected unlock Signed-off-by:

No need to increment each UDS_ error code manually (relative to UDS_ERROR_CODE_BASE). Also, remove unused PRP_BLOCK_START and PRP_BLOCK_END. Lastly, UDS_SUCCESS and VDO_SUCCESS are used interchangeably; so best to explicitly set VDO_SUCCESS equal to UDS_SUCCESS. Signed-off-by:

The vdo_page_cache's 'vdo' is the same as the block_map's vdo instance, so use that to save 2 extra dereferences. Signed-off-by:

Requires moving dm-vdo-target.c into drivers/md/dm-vdo/ This change adds a proper drivers/md/dm-vdo/Makefile and eliminates the abnormal use of patsubst in drivers/md/Makefile -- which was the cause of at least one build failure that was reported by the upstream build bot. Also, split out VDO's drivers/md/dm-vdo/Kconfig and include it from drivers/md/Kconfig Signed-off-by:

Use get_unaligned_le64() on the hash lock's record name to serve as the key to use with the int hash-map. Switching to using int hash-map removes the only consumer of pointer hash-map, as such it is removed. Reviewed-by:
