This brings right back up the libinux idea. There are continued
concerns about type compatibility, but saying "oh, use syscall(3)
instead" has worse properties than a Linux-kernel-team maintained
libinux. Last I heard the glibc team had (reluctantly?) agreed to do
something to deal with linux-specific system calls, but last I heard
nothing had happened. The last discussion I see on the glibc mailing
list dates back to November, and that thread seems to have died from
bikeshedding, again.
There aren't a *lot* of such system calls, but even in that thread the
"oh, only two applications need this, let them use syscall(3)" seems to
remain.
