From 15362d69c4c88a8f1762b319281c976d293cfe47 Mon Sep 17 00:00:00 2001 From: Jeremy Kerr Date: Mon, 12 Feb 2018 15:45:40 +1030 Subject: fsi: Add fsi_master_rescan() We'll want non-core fsi code to trigger a rescan, so introduce a non-static fsi_master_rescan() function. Use this for the existing unscan/scan behaviour too.
