[v2,0/3] add trace_seq_reset function

Message

This series is a prerequisite for a later effort of making trace_seq more
flexible about its buffer size. To achieve that, initializing and resetting
the buffers need to be differentiated.

Ricardo B. Marliere (3):
  tracing: add trace_seq_reset function
  tracing: initialize trace_seq buffers
  tracing: convert __trace_seq_init to use WARN_ON_ONCE
