Subject: tracing: Use strlcpy() instead of strcpy() in __trace_find_cmdline()

From: Amey Telawane <[email protected]>

commit e09e28671cda63e6308b31798b997639120e2a21 upstream.

Strcpy is inherently not safe, and strlcpy() should be used instead. __trace_find_cmdline() uses strcpy() because the comms saved must have a terminating nul character, but it doesn't hurt to add the extra protection of using strlcpy() instead of strcpy().
