I was going to let this pass, but since Greg flagged it...
It's sufficient given the context (it's the tail end of a series of
patches), but it's preferable to allude to the other patches in a case
like this. For example:
Now we have sorted symbols, we can use binary search for
kallsyms lookups as well.
(1) "Now we have sorted symbols" indicates to the reader that this has
just recently become possible.
(2) "as well." indicates that this was not the main justification for
sorting the symbols.
Ideally you would add some numbers, like so:
On my machine 'cat /proc/kallsyms' only takes 0.02 seconds, but
this halves it to 0.01 seconds.
(That's my results under kvm, which is a poor way to do timing, but you
get the idea).
Thanks,
Rusty.
