Hi Dan,

> smatch warnings:

Thanks for the report! I've sent a fix, you're CCed.

However, I can 't seem to recreate the smatch warning; could you include
the build command you're using for these? I've tried with

    make [...] C=1 CHECK=/path/to/smatch

using smatch 4f2585888, but that doesn't report the error you've listed
there. Do I need any specific CHECKFLAGS?

Cheers,

Jeremy
