To replace unix_table_lock with per-hash locks in the next patch, we need
to save a hash in each socket because /proc/net/unix or BPF prog iterate
sockets while holding a hash table lock and release it later in a different
function.
Currently, we store a real/pseudo hash in struct unix_address. However, we
do not allocate it to unbound sockets, nor should we do just for that. For
this purpose, we can use sk_hash. Then, we no longer use the hash field in
struct unix_address and can remove it.
Also, this patch does
- rename unix_insert_socket() to unix_insert_unbound_socket()
- remove the redundant list argument from __unix_insert_socket() and
unix_insert_unbound_socket()
- use 'unsigned int' instead of 'unsigned' in __unix_set_addr_hash()
- remove 'inline' from unix_remove_socket() and
unix_insert_unbound_socket().

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
