Subject: [PATCH 4.9 066/141] driver/dma/ioat: Call del_timer_sync() without holding prep_lock
Date: Sun, 11 Nov 2018 14:25:25 -0800	[thread overview]
Message-ID: <20181111221636.985001667@linuxfoundation.org> (raw)
In-Reply-To: <20181111221627.853046496@linuxfoundation.org>

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

[ Upstream commit cfb03be6c7e8a1591285849c361d67b09f5149f7 ]

[ 1223.813492] 4 locks held by systemd-shutdow/1:
[ 1223.834677]  #0:  (reboot_mutex){+.+.}, at: [<0000000056d33456>] SYSC_reboot+0x10f/0x300

In the ioat_shutdown() function:

	spin_lock_bh(&ioat_chan->prep_lock);
	set_bit(IOAT_CHAN_DOWN, &ioat_chan->state);
	del_timer_sync(&ioat_chan->timer);
	spin_unlock_bh(&ioat_chan->prep_lock);

According to the synchronization rule for the del_timer_sync() function,
the caller must not hold locks which would prevent completion of the
timer's handler.

The timer structure has its own lock that manages its synchronization.
Setting the IOAT_CHAN_DOWN bit should prevent other CPUs from
trying to use that device anyway, there is probably no need to call
del_timer_sync() while holding the prep_lock. So the del_timer_sync()
call is now moved outside of the prep_lock critical section to prevent
the circular lock dependency.
