From c6a9d7b55e2df63de012a9a285bf2a0bee8e4d59 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 11 Jun 2009 09:49:15 -0400 Subject: [PATCH] ring-buffer: remove useless warn on check A check if "write > BUF_PAGE_SIZE" is done right after a if (write > BUF_PAGE_SIZE) return ...; Thus the check is actually testing the compiler and not the kernel. This is useless, remove it.
