After commit 6bfd0133bee2 ("btrfs: raid56: switch scrub path to use a
single function"), the raid56 implementation no longer uses different
endio functions for RMW/recover/scrub.
All read operations end in submit_read_wait_bio_list(), while all write
operations end in submit_write_bios(). This means quite some trace
events are out-of-date and no longer utilized.
This patch would unify the trace events into just two:
- trace_raid56_read()
Replaces trace_raid56_read_partial(), trace_raid56_scrub_read() and
trace_raid56_scrub_read_recover().
- trace_raid56_write()
Replaces trace_raid56_write_stripe() and
trace_raid56_scrub_write_stripe().
