From 00f198de6b6ac663926bff2666d956a61cea85db Mon Sep 17 00:00:00 2001 From: Tom Caputi Date: Tue, 18 Dec 2018 17:47:33 -0500 Subject: Fix zfs_dirty_data_sync_percent documentation In dfbe2675 zfs_dirty_data_sync was changed to a new tunable named zfs_dirty_data_sync_percent. Unfortunately, the module parameter documentation is the code was not updated accordingly. This patch simply corrects that.
