Subject: [PATCH] Btrfs: remove redundant btrfs_balance_delayed_items
Date: Fri, 20 Oct 2017 17:53:41 -0600	[thread overview]
Message-ID: <20171020235341.17019-1-bo.li.liu@oracle.com> (raw)

In functions like btrfs_create(), we run both
btrfs_balance_delayed_items() and btrfs_btree_balance_dirty() after
the operation, but btrfs_btree_balance_dirty() is surely going to run
btrfs_balance_delayed_items().

This keeps only btrfs_btree_balance_dirty().
