>From what I recall when we were looking into reiserfs on S/390,
the core problem was that reiserfs tried to do *atomic* operations
on non-aligned words. This isn't supported by the hardware on
S/390 (normal non-aligned accesses just work).
I don't really see how this can be fixed in a trap handler; how
would the handler guarantee atomicity?
Oh thats different! That won't even work %100 correctly on x86. On
x86 it will "execute", but it won't be atomic.
Why the F*CK does it need to do this? It sounds like sloppy
programming to me.
