Re: [libvirt] [PATCH] nodeinfo: fix detection of physical memory on uclibc/musl libc

The gnulib's physmem_total will as a fallback report 64MB as

it impossible to detect if physmem_total works or not, so we try first
the linux only sysinfo(2) before falling back to gnulibs physmem_total.
This makes the total memory be correctly reported on musl libc and
uclibc.

I think you should instead patch the gnulib physmem_total() function
to support use of sysinfo() itself. That way all the many users of
GNULIB will work correctly on musl/uclibc, rather than just libvirt.
