[RFC PATCH 61/62] sockfs: switch to ->free_inode()

[Al Viro]

From: Al Viro <v...@zeniv.linux.org.uk>

we do have an RCU-delayed part there already (freeing the wq),
so it's not like the pipe situation; moreover, it might be
worth considering coallocating wq with the rest of struct sock_alloc.
->sk_wq in struct sock would remain a pointer as it is, but
the object it normally points to would be coallocated with
struct socket...
