Subject: Btrfs: remove redundant btrfs_balance_delayed_items
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1805f2ca3f27f25c8e637edc4b40bab237f9d07c;p=openwrt%2Fstaging%2Fblogic.git

Btrfs: remove redundant btrfs_balance_delayed_items

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().
