Subject: [PATCH 23/36] btrfs: make sure we create all new bgs
Date: Tue, 11 Sep 2018 13:57:54 -0400 [thread overview]
Message-ID: <20180911175807.26181-24-josef@toxicpanda.com> (raw)
In-Reply-To: <20180911175807.26181-1-josef@toxicpanda.com>
Allocating new chunks modifies both the extent and chunk tree, which can
trigger new chunk allocations. So instead of doing list_for_each_safe,
just do while (!list_empty()) so we make sure we don't exit with other
pending bg's still on our list.
