tracing/events: change the type of __str_loc_item to unsigned short
When defining a dynamic size string, we add __str_loc_##item to the trace entry, and it stores the location of the actual string in entry->_str_data[] 'unsigned short' should be sufficient to store this information, thus we save 2 bytes per dyn-size string in the ring buffer. [ Impact: reduce memory occupied by dyn-size strings in ring buffer ] Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Cc: Steven Rostedt <rostedt@goodmis.org> LKML-Reference: <4A14EDB6.2050507@cn.fujitsu.com> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>
