Package: libc6
Version: 2.9-12
Severity: normal
glibc-2.9 unnecssarily breaks compatibility with older kernels and
eventfd/signalfd.
with glibc-2.7 and 2.8, eventfd and signalfd work with kernels <2.6.27, as
they call the old syscall number.
glibc-2.9 *only* calls the newer syscall number.
that means that programs that could get eventfd's/signalfds with an older
libcs cannot do so with newer ones, even though the kernel supports it.
it would be better if glibc fell back to the old syscall when the new one
returns ENOSYS, or calls the old one first if flags == 0.

This bug has been closed in version 2.9-22, but has not been closed due
to a typo in the changelog. Closing it manually.
