one-include.patch

实现了poll/epoll/devpoll等C++封装

######### 
   sample patch for /usr/include to use Vitaly Luban's O_ONESIGFD patch.
   Needed on systems where /usr/include/ does not point into 
   /usr/src/linux/include for anything; carries the userspace visible 
   constants into the userspace glibc headers.

   It can't be folded into Vitaly's patch because it's patching
   /usr/include rather than /usr/src/linux.
