Subject: [PATCH 17/17] arch: rename copy_thread_tls() back to copy_thread()
Date: Tue, 23 Jun 2020 01:43:26 +0200	[thread overview]
Message-ID: <20200622234326.906346-18-christian.brauner@ubuntu.com> (raw)
In-Reply-To: <20200622234326.906346-1-christian.brauner@ubuntu.com>

Now that HAVE_COPY_THREAD_TLS has been removed, rename copy_thread_tls()
back simply copy_thread(). It's a simpler name, and doesn't imply that only
tls is copied here. This finishes an outstanding chunk of internal process
creation work since we've added clone3().
