look at my
latest patches to see how it's done. We can preempt softirq
handlers via lock-break methods. The same method doesnt work in the idle
Are you referring to this patch?
http://people.redhat.com/mingo/voluntary-preempt/defer-softirqs-2.6.8-rc2-A2 Surely something similar could easily be done for irq
context softirq
processing with a patch like my earlier one? And it would prevent
spilling to ksoftirq when a RT thread isn't waiting to run.
the softirq-defer patch is just the first step to enable lock-break of
softirqs - the lock-break is done in the -I1 patch.
(what patch do you refer to via 'my earlier one'? Did you mean your 'if
(rt_task())' suggestion?)
