Manjaro kernel patches?

I tried to find information on manjaro kernel and if there are any patches applied to it on top of vanilla kernel but no luck.
Does anyone knows how or if manjaro kernel is modified in comparison to vanilla arch kernel?

I'm interested in building a manjaro kernel with TuxOnlce (no occasional hibernation/suspend issues with X - great thing for laptops) and BFQ (I/O scheduler for quicker memory management and thus speeding system) but I'm not sure which patches are already applied if any. There is no Tux patch in manjaro but not sure about BFQ.

See PKBUILDs here:

BFQ is enabled in Manjaro kernels AFAIK

Yes, Manjaro kernels have the latest BFQ patchset.

Thanks for the info. I thought I could speed up my system even more but I guess it's as quick as possible then .
Only TuxOnlce would be needed in such case.

However when I look on PKGBUILD of kernel 4.4 I can see only:
'aufs4-base.patch'
'aufs4-kbuild.patch'
'aufs4-loopback.patch'
'aufs4-mmap.patch
'aufs4-standalone.patch'

No BFQ but I might not look on the right part. I'm newbie at this so bare with me.

Just run cat /sys/block/sda/queue/scheduler to be completely sure

OK, I got: noop deadline cfq [bfq]
I guess that's all right. Thanks
