From 2e4e97abac4c95f8b87b2912ea013f7836a6f10b Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 5 Nov 2021 16:45:29 -0400 Subject: [PATCH] btrfs: pass fs_info to trace_btrfs_transaction_commit The root on the trans->root can be anything, and generally we're committing from the transaction kthread so it's usually the tree_root. Change this to just take an fs_info, and to maintain compatibility simply put the ROOT_TREE_OBJECTID as the root objectid for the tracepoint. This will allow use to remove trans->root.
