[uml-devel] NPTL + UML?

[uml-devel] NPTL + UML?

[La Monte H.P. Yarroll]

Is anybody out there working on getting thread-local storage (i.e. NPTL) 
working with UML?  I see that set_thread_area(2) and get_thread_area(2) 
are both sys_ni_syscall in arch/um/kernel/sys_call_table.c.

The lack of NPTL support causes me a lot of grief...

I did start to look at it, but ran into trouble with (possibly unrelated)
bugs, I didn't succeed in debugging. In principle it should be easy to do
by passing on the system call to the parent kernel (perhaps via ptrace).

I've punted on some of the new 2.6 stuff for now.  I'll catch up on that
and other things (modules, hugetlbfs, etc) when I get a free moment or two.
