From 975750a98c26769fe54785579f4b26c961a7a6f4 Mon Sep 17 00:00:00 2001 From: Toshi Kani Date: Mon, 12 Jun 2017 16:25:11 -0600 Subject: libnvdimm, pmem: Add sysfs notifications to badblocks Sysfs "badblocks" information may be updated during run-time that: - MCE, SCI, and sysfs "scrub" may add new bad blocks - Writes and ioctl() may clear bad blocks Add support to send sysfs notifications to sysfs "badblocks" file under region and pmem directories when their badblocks information is re-evaluated (but is not necessarily changed) during run-time.
