Bug#496871: linux-2.6: please change the PREEMPT settings
Bugs #292061 and #311185 are contradictory. One asks for it to be disabled, the other enabled.
I spoke with Simon Horman and he said:
<wildfire> horms, why doesn't the debian linux kernel set preempt to on?
<horms> wildfire: nfi
<horms> i believe back in my day it was too experimental
<horms> but i have no idea why it is still off
We also checked a few other distributions:
Ubuntu (feisty): CONFIG_PREEMPT_VOLUNTARY=y/CONFIG_PREEMPT_BKL=y
RHEL 5.1: CONFIG_PREEMPT_VOLUNTARY=y, CONFIG_PREEMPT_BKL=y
master.kernel.org: CONFIG_PREEMPT_NOTIFIERS=y, CONFIG_PREEMPT_VOLUNTARY=y
(all machines are either ia64 or x86_64)
So the censensus would seem to be to set:
CONFIG_PREEMPT_NOTIFIERS=y (already set in Debian)
Could you please make it so, and close out the two above-mentioned reports?
