Subject: btrfs: record delayed inode root in transaction
From: Boris Burkov <boris@xxxxxx>
commit 71537e35c324ea6fbd68377a4f26bb93a831ae35 upstream.
When running delayed inode updates, we do not record the inode's root in
the transaction, but we do allocate PREALLOC and thus converted PERTRANS
space for it. To be sure we free that PERTRANS meta rsv, we must ensure
that we record the root in the transaction.
Fixes: 4f5427ccce5d ("btrfs: delayed-inode: Use new qgroup meta rsv for delayed inode and item")
