From daddef76c3deaaa7922f9d7b18edbf0a061215c3 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Wed, 15 Jun 2016 11:14:53 +0200 Subject: [PATCH] net: Don't forget pr_fmt on net_dbg_ratelimited for CONFIG_DYNAMIC_DEBUG The implementation of net_dbg_ratelimited in the CONFIG_DYNAMIC_DEBUG case was added with 2c94b5373 ("net: Implement net_dbg_ratelimited() for CONFIG_DYNAMIC_DEBUG case"). The implementation strategy was to take the usual definition of the dynamic_pr_debug macro, but alter it by adding a call to "net_ratelimit()" in the if statement. This is, in fact, the correct approach. However, while doing this, the author of the commit forgot to surround fmt by pr_fmt, resulting in unprefixed log messages appearing in the console. So, this commit adds back the pr_fmt(fmt) invocation, making net_dbg_ratelimited properly consistent across DEBUG, no DEBUG, and DYNAMIC_DEBUG cases, and bringing parity with the behavior of dynamic_pr_debug as well.
