Is there a reason to use the zlib and nothing but the zlib for the
cryptolib? RFCs 1950 - 1952? Or would any form of compression do, in
principle at least?
Because it's not very sensible to have 2 pieces of code that
do exactly the same thing? :-)
In the worst case, I consider it not too hard to add a wrapper
interface to the zlib to do the scatter-gather handling.
It's not that simple.
Is the wrapper called in IRQ or BH or user context? This matters
to determine what kind of kmap() operations you must use in the
wrapper.
That's merely the beginning of the problems with this kind of idea.
Don't let my statements stall your work, it was just a FYI and
something we should take care of in the 2.7.x timeframe not now.
