From: Johannes Berg Date: Thu, 11 Apr 2013 18:48:09 +0000 (+0200) Subject: backports: dissolve compat-3.9.h X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=33b2d02fb520d39a9a96ffc5e63de06df8a75c75;p=openwrt%2Fstaging%2Fblogic.git backports: dissolve compat-3.9.h Move everything into the appropriate header files. Also include uidgid.h into the new fs.h since kernels that had uidgid.h include it already, so it doesn't change anything there, but those that don't have it obviously can't have included it and people rely on it behing included there.
