> ( from http://lkml.org/lkml/2007/3/16/407 and the file > http://people.redhat.com/roland/utrace/2.6-current/utrace-tracehook-um.patch ) AFAIK Jeff's patch just eliminates ptrace code from um arch. I tried it some time ago, it worked but ptrace was missing. I don't know if something got broken from the time of the test. renzo
