From 20a5239a5d0f340e29827a6a2d28a138001c44b8 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Mon, 14 Dec 2009 22:01:12 +0000 Subject: [PATCH] Btrfs: Show discard option in /proc/mounts Christoph's patch e244a0aeb6a599c19a7c802cda6e2d67c847b154 doesn't display the discard option in /proc/mounts, leading to some confusion for me. Here's the missing bit.
