From 46cc8ba30445025f0ed3ed9f429aea573b301122 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Tue, 25 Aug 2015 16:59:16 -0400 Subject: [PATCH] nfsd: don't WARN/backtrace for invalid container deployment. These messages, combined with the backtrace they trigger, makes it seem like a serious problem, though a quick search shows distros marking it as a "won't fix" non-issue when the problem is reported by users. The backtrace is overkill, and only really manages to show that if you follow the code path, you can't really avoid it with bootargs or configuration settings in the container. Given that, lets tone it down a bit and get rid of the WARN severity, and the associated backtrace, so people aren't needlessly alarmed. Also, lets drop the split printk line, since they are grep unfriendly. Signed-off-by: Paul Gortmaker Signed-off-by: J.
