Analyze and fix the following issue in the Linux kernel code: trace/blktrace: fix memory leak with using debugfs_lookup()
Problem Details: When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time.

However, tun_chr_open() passes a `struct socket` embedded in a `struct tun_file` allocated with sk_alloc(). This causes a type confusion when issuing a container_of() w...
