Subject: [39/55] powerpc/pseries/hvconsole: Fix dropped console output
Date: Fri, 05 Aug 2011 17:02:09 -0700 [thread overview]
Message-ID: <20110806000252.787677814@clark.kroah.org> (raw)
In-Reply-To: <20110806000257.GA25498@kroah.com>
2.6.32-longterm review patch. If anyone has any objections, please let us know.
------------------
From: Anton Blanchard <anton@samba.org>
commit 51d33021425e1f905beb4208823146f2fb6517da upstream.
Return -EAGAIN when we get H_BUSY back from the hypervisor. This
makes the hvc console driver retry, avoiding dropped printks.
