From 9073868376ed5fa1f247327ccb2e6f766d5b7eed Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 9 Oct 2007 14:58:33 +0900 Subject: [PATCH] libata: wrap schedule_timeout_uninterruptible() in loop Tasks in uninterruptible sleep might be woken up by unrelated events and should check whether the condition it was waiting for has actually triggered. Wrap schedule_timeout_uninterruptible() in loop to achieve it.
