hehe lol :)

same for me. Just some theoretical stuff.

well, -mm is easy (yet) to follow, it has mainly tons of bugfixes and 4g/4g 
and such. But the problem is, if you merge tons of extra features like I do 
with WOLK and want to have features like: PaX, grsec, uml-skas etc. the 
problem is to understand the code at all and merge all things up so it works 
nicely (I am far away from understanding it all, it's often a try-and-error 
session ;) ...

		That's the most timeconsuming problem I have.

Sometimes I need days to understand something in mm/ or the assembler stuff in 
the kernel when I play around with PaX.

The problem is not merging patches itself, the problem is adding huge features 
like PaX, rmap, O(1), VM fixes and such so everything works nicely, fix 
rejects, fix code overlaps or complete incompatibilities.

You just said it some days ago about uml-skas vs. PaX.

Maintaining just patches which people are sending is trivial. Just mentioning: 
wolk4.11 has 1598 patches applied where ~ 1000 are just fixes for fixes and 
fixesfixes and similar ;)

ciao, Marc
