From 266c81a910540d85cc47463b2a0cb16b0dd4e1e1 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Wed, 7 May 2014 17:38:00 +0200 Subject: btrfs-progs: balance filter: add limit of processed chunks Add more control to the balance behaviour. Usage filter may not be finegrained enough and can lead to moving too many chunks at once. Another example use is in connection with drange+devid or vrange filters that allow to work with a specific chunk or even with a chunk on a given device. The limit filter applies last, the value of 0 means no limiting.
