There were 2 patches in v1 that were flagged by the 0day robot for
strncpy off-by-1 warnings:

  tracing: Remove size restriction on hist trigger cmd error logging
  tracing: Remove size restriction on synthetic event cmd error logging

  warning: 'strncpy' output truncated before terminating nul copying
  as many bytes from a string as its length [-Wstringop-truncation]

This v2 patchset consists of just those two patches with the fix for
those warnings.

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
