X-Git-Tag: v2.6.26-rc1~1158^2~24 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=c2e8b8531b162fb314434f1f2608ba1ddf46b98f;p=linux-2.6-omap-h63xx.git [S390] exec_protect: Fix incorrect extern declarations. sys_sigreturn and sys_rt_sigreturn don't take any arguments. So luckily this resulted only in unneeded instead of incorrect code. But still this clearly shows why one should not put extern declarations in C files (will be fixed with a larger sparse patch).
