Subject: btrfs: remove pointless initialization at btrfs_qgroup_trace_extent()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=287d1cf303dc1521de531b63f4123ba9f5b792dc;p=users%2Fwilly%2Fxarray.git

btrfs: remove pointless initialization at btrfs_qgroup_trace_extent()

The qgroup record was allocated with kzalloc(), so it's pointless to set
its old_roots member to NULL. Remove the assignment.
