You're right. It's much easier to use it than spinlock implementation from 
Linux kernel.

I test it (in my github fork of) LTP project [1], but unfortunately some tests 
which heavy
test it fails.

$ ./test09
test09.c:53: INFO: Joining thread 63
test09.c:61: FAIL: Atomic does not have expected value

The tests just get slightly fewer incrementation than it should get (6373821 
instead of 640).

The implementation in github is for SPARC32, but I adjusted the code to test it 
on SPARC64
and (of course) it behaves the same.

Any idea what can be wrong?


Kind regards,
Petr

About grub.conf the header section ...

### BEGIN /etc/grub.d/00_header ###

at

if [ x$feature_default_font_path = xy ] ; then
   font=unicode
else
insmod part_sun
insmod part_sun
insmod diskfilter
insmod mdraid1x
insmod ext2

The part_sun module is called twice.

Thanks,
