From 6442550027f77a76efa7873b946c34c4a733febd Mon Sep 17 00:00:00 2001 From: Naohiro Aota Date: Mon, 19 Jun 2023 11:15:31 +0900 Subject: [PATCH] btrfs: tracepoints: also show actual number of the outstanding extents The btrfs_inode_mod_outstanding_extents trace event only shows the modified number to the number of outstanding extents. It would be helpful if we can see the resulting extent number as well.
