eventpoll.h: fix epoll event masks (6f051e4a) · Commits · 戴 / test

[resend due to me forgetting to cc: linux-api the first time around I posted these back on Feb 23] From: Greg Kroah-Hartman <gregkh@linuxfoundation.org> When userspace tries to use these defines, it complains that it needs to be an unsigned 1 that is shifted, so libc implementations have to create their own version. Fix this by defining it properly so that libcs can just use the kernel uapi header. Reported-by:
