Well it's a mess alright.
Unfortunately we cannot declare that we'll stay on 2.4 forever.
Several subsystems *MTD gough* do not support latest hw, or
the developers have moved on to 2.6 full time, refusing to
bother with 2.4 anymore.
Can we make an effort to pinpoint the performance
bottlenecks & re-implement the affected areas sanely?
The -tiny patchset is a start, but frankly I don't think it's
code/data footprint that it's the problem.
IMHO it's not just the small embedded systems that have been
affected; just on them the effects are more obvious.
So what do you all think?
Regards
Pantelis
