Hello,

Maybe it is not appropriate, but util-linux and udev (eudev) needs the
cpuset / affinity support. I hope this can be added soon on musl.

Thanks,
Matias.

eudev only seem to use affinity to get
a hint on the number of cpus and set the
max number of worker children accordingly
(a sensible default value will work for this)

and libudev has a 'cpu_set_malloc' api
which uses affinity to get the right cpu
set size, but it is never used
(dummy api will work)

so affinity does not seem to be essential for eudev

It's been on the agenda for a long time now. Maybe I can look at doing
it in the next few days.

echo /sys/devices/system/cpu/cpu[0-9]* | wc -w
