+What:		/sys/firmware/acpi/hotplug/force_remove
+Date:		Mar 2017
+Contact:	Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+Description:
+		Since the force_remove is inherently broken and dangerous to
+		use for some hotplugable resources like memory (because ignoring
+		the offline failure might lead to memory corruption and crashes)
+		enabling this knob is not safe and thus unsupported.

 Date:		May 2011
 Contact:	Martin K. Petersen <martin.petersen@oracle.com>
 Description:
-		Devices that support discard functionality may return
-		stale or random data when a previously discarded block
-		is read back. This can cause problems if the filesystem
-		expects discarded blocks to be explicitly cleared. If a
-		device reports that it deterministically returns zeroes
-		when a discarded area is read the discard_zeroes_data
-		parameter will be set to one. Otherwise it will be 0 and
-		the result of reading a discarded area is undefined.
+		Will always return 0.  Don't rely on any specific behavior
+		for discards, and don't read this file.
