blktrace/tracing: Use trace_seq_has_overflowed() helper function
Checking the return code of every trace_seq_printf() operation and having to return early if it overflowed makes the code messy. Using the new trace_seq_has_overflowed() and trace_handle_return() functions allows us to clean up the code. In the future, trace_seq_printf() and friends will be turning into void functions and not returning a value. The trace_seq_has_overflowed() is to be used instead. This cleanup allows that change to take place. Cc: Jens Axboe <axboe@fb.com> Reviewed-by:Petr Mladek <pmladek@suse.cz> Signed-off-by:
