Please post patches inline so they're easier to comment on.
Attachments are a nuisance.
Sorry about that. I've had problems in the past with my email client
word wrapping patches, so to be sure the patch goes untouched I sent it
this way.
Since I've changed email client since then, next time I'll try inlining
again.
Am I correct that this is completely replacing stem compression with
your substring dictionary approach?
Yes, you are correct.
Right now I'm working on making the proc interface more eficient by
removing all the seq_file stuff, that was needed because of the O(n)
lookup time we had previously.
Not using seq_file with stem decompression would make a simple "cat
/proc/kallsyms" to be O(n^2).
