[PATCH] lockdep: remove extra "irq" string

[Peter Zijlstra]

Subject: lockdep: remove extra "irq" string
From: Peter Zijlstra <a.p.zijlstra@xxxxxxxxx>
Date: Wed Mar 04 14:53:24 CET 2009

print_irq_inversion_bug() gets handed state strings of the form

  "HARDIRQ", "SOFTIRQ", "RECLAIM_FS"

and appends "-irq-{un,}safe" to them, which is either redudant for *IRQ or
confusing in the RECLAIM_FS case.
