From b01c3a0010aabadf745f3e7fdb9cab682e0a28a2 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Fri, 23 Mar 2012 15:41:20 +0100 Subject: perf: Move mmap page data_head offset assertion out of header Having the build time assertion in header is making the perf build fail on x86 with: ../../include/linux/perf_event.h:411:32: error: variably modified \ ‘__assert_mmap_data_head_offset’ at file scope [-Werror] I'm moving the build time validation out of the header, because I think it's better than to lessen the perf build warn/error check.
