Subject: [RFC v4 7/8] binder: use __kernel_pid_t and __kernel_uid_t for userspace
Date: Mon, 28 Mar 2022 03:59:46 +0000	[thread overview]
Message-ID: <20220328035951.1817417-8-tjmercier@google.com> (raw)
In-Reply-To: <20220328035951.1817417-1-tjmercier-hpIqsD4AKlfQT0dZR+AlfA@public.gmane.org>

The kernel interface should use types that the kernel defines instead of
pid_t and uid_t, whose definiton is owned by libc. This fixes the header
so that it can be included without first including sys/types.h.
