Subject: [PATCH 6.1 281/325] af_unix: Kconfig: make CONFIG_UNIX bool

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alexander Mikhalitsyn <aleksandr.mikhalitsyn@...onical.com>

commit 97154bcf4d1b7cabefec8a72cff5fbb91d5afb7b upstream.

Let's make CONFIG_UNIX a bool instead of a tristate.
We've decided to do that during discussion about SCM_PIDFD patchset [1].
