Subject: [PATCH 5.4 095/135] btrfs: do not check delayed items are empty for single transaction cleanup
From: Josef Bacik <josef@...icpanda.com>
commit 1e90315149f3fe148e114a5de86f0196d1c21fa5 upstream.
btrfs_assert_delayed_root_empty() will check if the delayed root is
completely empty, but this is a filesystem-wide check. On cleanup we
may have allowed other transactions to begin, for whatever reason, and
thus the delayed root is not empty.
So remove this check from cleanup_one_transation(). This however can
stay in btrfs_cleanup_transaction(), because it checks only after all of
the transactions have been properly cleaned up, and thus is valid.
