From cf2731e65b2015988b2cae7970886279e11b013f Mon Sep 17 00:00:00 2001 From: Gaurav Kumar Date: Wed, 27 Jul 2016 14:27:31 -0700 Subject: arc_meta_limit should be updated when arc_max is changed. When arc_max is increased, arc_meta_limit will not be updated to 3/4 of the new arc_c_max value. This was done originally to preserve any existing maximum value. This turned out to be counter intuitive to users and this fix changes that behavior. If zfs_arc_meta_limit is non-default, it will be picked up later in the ARC tuning function.
