Date: Thu, 28 Jul 2011 16:44:18 -0700 (PDT) From: Andi Kleen <andi@...stfloor.org> To: anton@...ba.org, benh@...nel.crashing.org, ak@...ux.intel.com, linux-kernel@...r.kernel.org, stable@...nel.org, tim.bird@...sony.com Subject: [PATCH] [14/50] powerpc/pseries/hvconsole: Fix dropped console output 2.6.35-longterm review patch. If anyone has any objections, please let me know. ------------------ From: Anton Blanchard <anton@...ba.org> [ upstream commit 51d33021425e1f905beb4208823146f2fb6517da ] Return -EAGAIN when we get H_BUSY back from the hypervisor. This makes the hvc console driver retry, avoiding dropped printks.
