[PATCH 01/43] xfs: prepare refcount btree cursor tracepoints for realtime

Darrick J. Wong
2024-12-13T01:10:31Z

From: Darrick J. Wong <djwong@kernel.org>

Rework the refcount btree cursor tracepoints in preparation to handle the
realtime refcount btree cursor. Mostly this involves renaming the field to
"refcbno" and extracting the group number from the cursor when possible.
