Internal lsof uses inode numbers on socket fs to resolve the type of sockets. Files under /proc/net/, such as tcp, udp, unix, etc provides such inode information. Unfortunately bluetooth related protocols don't provide such inode information. This patch series introduces /proc/net files for the protocols. This patch against af_bluetooth.c provides facility to the implementation of protocols. This patch extends bt_sock_list and introduces two exported function bt_procfs_init, bt_procfs_cleanup. The type bt_sock_list is already used in some of implementation of protocols. bt_procfs_init prepare seq_operations which converts protocol own bt_sock_list data to protocol own proc entry when the entry is accessed. What I, lsof user, need is just inode number of bluetooth socket. However, people may want more information. The bt_procfs_init takes a function pointer for customizing the show handler of seq_operations. In v4 patch, __acquires and __releases attributes are added to suppress sparse warning. Suggested by Andrei Emeltchenko. In v5 patch, linux/proc_fs.h is included to use PDE. Build error is reported by Fengguang Wu.
