If possible, please reverse the order of includes to first include glibc
headers and then Linux kernel uapi ones.
Kernel uapi headers did not declare their header file dependencies correctly
and I've been fixing them. I have also tried to fix compatibility issues
with glibc headers, but unfortunately they only work when glibc headers
are included before kernel headers. Userspace which has been relying on
the magic include order for various uapi headers is now unfortunately
affected. Sorry about that.
