In the Linux kernel, the following vulnerability has been resolved:btrfs: release path before inode lookup during the ino lookup ioctlDuring 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:WARNING: possible circular locking dependency detected
