FreeBSD had this value tunable before the switch to the new OpenZFS. The tunable name has changed, breaking legacy compat. Restore legacy compat for this tunable, properly expose the tunable with the new name on all platforms, and document it in zfs-module-parameters(5). While here, clean up the documentation for zfetch_max_distance a bit. Signed-off-by: Ryan Moeller <[email protected]>
