[PATCH 0/2] memory: Add tracepoints for log_sync

Posted by Peter Xu 4 years, 5 months ago

It can help to identify which step is slow for migration dirty sync process.
We have migration_bitmap_sync_* trace events but it's still a bit coarse.

This should help us to cut migration_bitmap_sync() into finer grained small
steps when measurement is needed.

Please review, thanks.
