From 16c01b20ae0572d5a1fe8059f1b4c09f79b73cbf Mon Sep 17 00:00:00 2001 From: Peng Tao Date: Wed, 23 Sep 2009 15:56:13 -0700 Subject: doc/filesystems: more mount cleanups Documentation/filesystems/sharedsubtree.txt needs updating because the mount command in util-linux package is well aware of shared subtree features now. The patch also fixes two typos in sharedsubtree.txt.
