From 118ce7ab9785846e1c673f6130bee526c127206c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 27 Feb 2014 19:51:54 +0100 Subject: atm: nicstar: remove interruptible_sleep_on_timeout We are trying to finally kill off interruptible_sleep_on_timeout. the two uses in the nicstar driver can be trivially replaced with wait_event_interruptible_lock_irq_timeout, which prevents the wake-up race and is able to check the buffer state with scq->lock held.
