[PATCH v3 0/2] Fix DM zone resource limits stacking

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is V2 of the patch 4/4 of the series "Zone write plugging and DM
zone fixes". This patch fixes DM zone resource limits stacking (max open
zones and max active zones limits). Patch 1 is new and is added to help
catch problems and eventual regressions of the handling of these limits.

Changes from v2:
 - Modify patch 1 to return an error for the case where the max open
   zones limit is greater than the max active zones limit.
 - Modify patch 2 to avoid duplicated actions on the limits and to
   remove warnings for unusual zone limits.

Changes from v1:
 - Added patch 1
 - Modified patch 2 to not cap the limits for a target with the number
   of sequential zones mapped but rather to use the device limits as is
   when more zones than the limits are mapped and 0 otherwise (no
   limits).

  block: Imporve checks on zone resource limits
  dm: Improve zone resource limits handling
