I believe that I answered that question in an earlier post, but
for what it's worth, the answer is an emphatic "yes": PREEMPTION
is turned on in GENERIC (along with _KPOSIX_PRIORITY_SCHEDULING
and SMB), and my (posted) kernel config is essentially include
GENERIC, turn off I486_CPU and I586_CPU, and override SCHED_ULE
(or not). So unless the config include mechanism is broken, I've
got PREEMPTION, (and so has nearly everyone else).
