Subject: [PATCH 1/2] btrfs: Ratelimit an info message
Date: Wed, 13 Jul 2016 16:19:14 +0300 [thread overview]
Message-ID: <1468415955-30804-1-git-send-email-kernel@kyup.com> (raw)
In-Reply-To: <20160713121526.GJ10595@twin.jikos.cz>
Recently during a crash it became apparent that this particular
message can be printed so many times that it causes the softlockup
detector to trigger. Fix it by ratelimiting it
