Hi I have just dono a (2nd version of the patch). This version uses smp_call_function, but don't grab any lock inside. I sent the version to the list. It is also at:
http://carpanta.dc.fi.udc.es/~quintela/kernel/2.4.0-test9-pre7/slab_02.patch
Could you test if it is now safe in SMP Sparc also???? (/me has no SMP Sparc's around nor knoledge about them :(
Later, Juan.
