| H A D | blktrace.c | f4a1d08c Wed Nov 12 10:35:48 CST 2014 Steven Rostedt (Red Hat) <rostedt@goodmis.org> 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.
