H A D | btrfs.h | dbb6ecb3 Tue Jun 20 02:06:05 CDT 2023 Qu Wenruo <wqu@suse.com> btrfs: tracepoints: simplify raid56 events
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 This means quite some trace events are out-of-date and no longer utilized.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().
