Subject: [RFC PATCH 01/12] powerpc/tm: Remove struct thread_info param from tm_reclaim_thread()
Date: Tue, 20 Feb 2018 11:22:30 +1100 [thread overview]
Message-ID: <20180220002241.29648-2-cyrilbur@gmail.com> (raw)
In-Reply-To: <20180220002241.29648-1-cyrilbur@gmail.com>
tm_reclaim_thread() doesn't use the parameter anymore, both callers have
to bother getting it as they have no need for a struct thread_info
either.
It was previously used but became unused in dc3106690b20 ("powerpc: tm:
Always use fp_state and vr_state to store live registers")
Just remove it and adjust the callers.
