[PATCH 5.12 184/700] btrfs: abort transaction if we fail to update the delayed inode

From: Greg Kroah-Hartman
Date: Mon Jul 12 2021 - 03:41:02 EST

[ Upstream commit 04587ad9bef6ce9d510325b4ba9852b6129eebdb ]

If we fail to update the delayed inode we need to abort the transaction,
because we could leave an inode with the improper counts or some other
such corruption behind.
