Subject: [PATCH 6.1 120/139] btrfs: release path before inode lookup during the ino lookup ioctl
Date: Wed, 20 Sep 2023 13:30:54 +0200 [thread overview]
Message-ID: <20230920112840.045080106@linuxfoundation.org> (raw)
In-Reply-To: <20230920112835.549467415@linuxfoundation.org>
6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
commit ee34a82e890a7babb5585daf1a6dd7d4d1cf142a upstream.
During the ino lookup ioctl we can end up calling btrfs_iget() to get an
inode reference while we are holding on a root's btree. If btrfs_iget()
needs to lookup the inode from the root's btree, because it's not
currently loaded in memory, then it will need to lock another or the
same path in the same root btree. This may result in a deadlock and
trigger the following lockdep splat:

Fix this simply by releasing the path before calling btrfs_iget() as at
point we don't need the path anymore.
