From 4f34b3bdf4ced8f808f6cd928b87bd42ea3039fe Mon Sep 17 00:00:00 2001 From: Cyril Plisko Date: Wed, 24 Oct 2012 12:26:56 +0200 Subject: [PATCH] zfs_scrub_limit tunable is not used anywhere As a part of scrub/resilver tuning zfs_scrub_limit fell out of use, but the definition of the variable remained in place. Moreover various guides still (misleadingly) mention it as a way to influence resilver/scrub behavior. This commit removes its finally.
