From c258d6e36442eb5d3363f6dbc0e6f2c162bfb66d Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Fri, 1 Mar 2019 10:47:58 +0800 Subject: btrfs: Introduce fs_info to extent_io_tree This patch will add a new member fs_info to extent_io_tree. This provides the basis for later trace events to distinguish the output between different btrfs filesystems. While this increases the size of the structure, we want to know the source of the trace events and passing the fs_info as an argument to all contexts is not possible. The selftests are now allowed to set it to NULL as they don't use the tracepoints.
