Subject: [git patch review 2/5] [IPoIB] use spin_trylock_irqsave()
Date: Mon, 31 Oct 2005 22:34:42 +0000	[thread overview]
Message-ID: <1130798082548-c351d7732f360685@cisco.com> (raw)
In-Reply-To: <1130798082548-646b24d6f405c5f5@cisco.com>

Use spin_trylock_irqsave() in ipoib_start_xmit() instead of
reinventing it out of local_irq_save(), spin_trylock() and
local_irq_restore().
