Re: Some Linux kernel config options
Hello.

CONFIG_PARAVIRT_SPINLOCKS
The help text suggests it should be enabled - yet that's not the
default! Unfortunately, enabling this will change the module ABI.
This mismatch seems like a bug so I filled
https://bugzilla.kernel.org/show_bug.cgi?id=94011 .
I found a very good written article about this option (why is it
needed, etc.) and benchmarks showing no impact on native performance:
http://wiki.xen.org/wiki/Benchmarking_the_new_PV_ticketlock_implementation .
And here shows big improvement when running one or two busy
virtualized guests: https://lkml.org/lkml/2012/3/23/50 .
Is it too late to enable it for Jessie?
CONFIG_NFSD_V4_SECURITY_LABEL
Help text says 'For now we recommend "Y" only for developers and
testers.'
Ouch! I looked in a different version of the kernel. Good thing in
current kernels it is stable now.
Thanks for your answer!
Bye.
