Revision 95c2b17534654829db428f11bcf4297c059a2a7e authored by Ben Hutchings on 26 September 2015, 11:23:56 UTC, committed by Thomas Gleixner on 01 October 2015, 10:18:13 UTC 
genirq: Fix race in register_irq_proc()
 
Per-IRQ directories in procfs are created only when a handler is first
added to the irqdesc, not when the irqdesc is created.  In the case of
a shared IRQ, multiple tasks can race to create a directory.  This
race condition seems to have been present forever, but is easier to
hit with async probing.
