Subject: [PATCH] IB/rdmavt: restore IRQs on error path in rvt_create_ah()
Date: Thu, 27 Apr 2017 12:14:20 +0300 [thread overview]
Message-ID: <20170427091420.j7kl5tmzqnyami4s@mwanda> (raw)
We need to call spin_unlock_irqrestore() instead of vanilla
spin_unlock() on this error path.
Fixes: 119a8e708d16 ("IB/rdmavt: Add AH to rdmavt")
