| Subject: [PATCH 1/2] eventpoll.h: fix epoll event masks |
| |
| 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. |
