From 5e096ef3b29e6113a7aa6a7dc4871987efa99bcb Mon Sep 17 00:00:00 2001 From: Vishal Verma Date: Mon, 30 Oct 2017 13:22:23 -0700 Subject: nfit_test: when clearing poison, also remove badrange entries The injected badrange entries can only be cleared from the kernel's accounting by writing to the affected blocks, so when such a write sends the clear errror DSM to nfit_test, also clear the ranges from nfit_test's badrange list. This lets an 'ARS Inject error status' DSM to return the correct status, omitting the cleared ranges.
