Exposing zfs_dirty_data_max directly doesn't make sense as its
a calculated value based off zfs_dirty_data_max_percent% of
all memory and capped at zfs_dirty_data_max_max.
Given this it could be limited via setting zfs_dirty_data_max_max.
The following could be exposed:-
zfs_dirty_data_max_max
zfs_dirty_data_max_percent
zfs_dirty_data_sync
zfs_delay_min_dirty_percent
zfs_delay_scale
Would that forfull your requirement?
Regards
Steve
