From a0ea787b027b79cf2e01c6758e5246db06520158 Mon Sep 17 00:00:00 2001 From: Jim Garlick Date: Tue, 3 Jan 2012 15:27:50 -0600 Subject: fs/9p: check schedule_timeout_interruptible return value In v9fs_file_do_lock() we need to check return value of schedule_timeout_interruptible() and exit the loop when it returns nonzero, otherwise the loop is not really interruptible and after the signal, the loop is no longer throttled by P9_LOCK_TIMEOUT.
