Btrfs_alloc_path should be matched with btrfs_free_path in error-handling code.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>

expression ra,rb;

when forall
when != btrfs_free_path(x,...)
\(return <+...x...+>; \| return@p2...; \) }
