Good finding. But, 't' is used while 'ctx' is unused in 'damon_split_region_at()' and 'damon_split_regions_of'. Below code change is also removing 'ctx', not 't'. Could you please update the commit message for that? Also, please fix the kernel test robot reported issues together: https://lore.kernel.org/damon/202208121823.8YTRPB1J-lkp@xxxxxxxxx/ Thanks, SJ [...]
