[dm-devel] [PATCH 1/2] dm zoned: Fix zone reclaim trigger

Triggerring reclaim only based on the percentage of unmapped cache zones can fail to detect cases where reclaim is needed, e.g. if the target has only 2 or 3 cache zones and only one unmapped cache zone, the percentage of free cache zone is higher than DMZ_RECLAIM_LOW_UNMAP_ZONES (30%) and reclaim

[dm-devel] [PATCH 2/2] dm zoned: Remove set but unused variables
