Add 3 new warnings to checkpatch:
1) PREFER_ETHER_ADDR_EQUAL
Replace memcmp(foo, bar, ETH_ALEN) with ether_addr_equal*()
2) PREFER_ETH_ZERO_ADDR
Replace memset(foo, 0, ETH_ALEN) with eth_zero_addr()
3) PREFER_ETH_BROADCAST_ADDR
Replace memset(foo, 0xFF, ETH_ALEN) with eth_broadcast_addr()
Suggest using eth_zero_addr() or eth_broadcast_addr() if memset is used instead.

Hello,
This series is aimed at addressing some of the futex hash bucket
lock hold times by introducing lockless wake-queues for futex_wake.
patch-1: introduces the lockless wake-queue machinery.
patch-2: makes use of patch 1 for futexes.
Details in the individual patches.
This was suggested
Given the overall futex architecture, any chance of reducing
hb-lock contention is welcome. In this particular case, using
wake-queues to enable lockless wakeups addresses very much real
world performance concerns, even cases of soft-lockups in cases
of large amounts of blocked tasks (which is not
From: Peter Zijlstra pet...@infradead.org
This is useful for locking primitives that can effect multiple
wakeups per operation and want to avoid lock internal lock contention
by delaying the wakeups until we've released the lock internal locks.
Alternatively it can be used to avoid issuing

Hi Guys,
Dongsu Park reported[1] that kernel oops can be triggered easily by
CPU plug when there is pending I/O on virtio-scsi.
Turns out two problems exist and both can trigger oops by CPU plug:

This looks like a long standing bug in all three 3ware drivers to
