From: Bart Van Assche <bart.vanassche@xxxxxxx>
Subject: block: make I/O timeout failure injection again task-independent
e41d58185f14 made all faults that are triggered from task context,
including I/O timeouts, dependent on the failure injection settings for
that task. Make it again possible to inject I/O timeout failures
independent of task context. An example for a fault injection for which
this patch makes a difference (from a VM booted with the 'threadirqs'
command line parameter):
FAULT_INJECTION: forcing a failure. name fail_io_timeout, interval 1, probability 100, space 0, times 1
CPU: 6 PID: 1253 Comm: irq/36-skd0-msi Not tainted 4.13.0-rc2-dbg+ #5
