From 90b1377daa9633973d595487d717d43d3c601420 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Wed, 27 Mar 2019 16:55:26 +0100 Subject: [PATCH] btrfs: qgroup: remove obsolete fs_info members The commit fcebe4562dec ("Btrfs: rework qgroup accounting") reworked qgroups and added some new structures. Another rework of qgroup mechanics e69bcee37692 ("btrfs: qgroup: Cleanup the old ref_node-oriented mechanism.") stopped using them and left uncleaned.
