* [PATCH net-next 0/2] net: phy: improve PHY suspend/resume
From: Heiner Kallweit @ 2018-05-23 19:28 UTC (permalink / raw)
To: Andrew Lunn, Florian Fainelli, David Miller; +Cc: netdev@vger.kernel.org
I have the issue that suspending the MAC-integrated PHY gives an
error during system suspend. The sequence is:
1. unconnected PHY/MAC are runtime-suspended already
2. system suspend commences
3. mdio_bus_phy_suspend is called
4. suspend callback of the network driver is called (implicitly
MAC/PHY are runtime-resumed before)
5. suspend callback suspends MAC/PHY
The problem occurs in step 3. phy_suspend() fails because the MDIO
bus isn't accessible due to the chip being runtime-suspended.
This series mainly adds a check to not suspend the PHY if the
MDIO bus parent is runtime-suspended.
Heiner Kallweit (2):
net: phy: improve check for when to call phy_resume in mdio_bus_phy_resume
net: phy: improve checks when to suspend the PHY

* [PATCH 33/33] random: convert to ->poll_mask
From: Christoph Hellwig @ 2018-05-23 19:20 UTC (permalink / raw)
To: viro; +Cc: Avi Kivity, linux-aio, linux-fsdevel, netdev, linux-api,

In-Reply-To: <20180523192022.1703-1-hch@lst.de>
The big change is that random_read_wait and random_write_wait are merged
into a single waitqueue that uses keyed wakeups. Because wait_event_*
doesn't know about that this will lead to occassional spurious wakeups
in _random_read and add_hwgenerator_randomness, but wait_event_* is
designed to handle these and were are not in a a hot path there.
