3.2.89-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Amey Telawane <ameyt@xxxxxxxxxxxxxx> 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().
