Hi Steve,

This is an assorted bunch of bugfixes addressing a bugzilla bug,
smatch warnings, and related things I found while fixing those.  In
particular, when looking at the bugzilla bug,
https://bugzilla.kernel.org/show_bug.cgi?id=215513, I noticed that the
err_log output looked truncated and looking further into it found that
it was, because the hist trigger command was very long, exceeding the
256 character limit.

Obviously that's too short, and the final 3 patches remove that
limitation.

Tom
