Subject: fs: Set the size of empty dirs to 0.

From: "Eric W. Biederman" <ebiederm@xmission.com>

commit 4b75de8615050c1b0dd8d7794838c42f74ed36ba upstream.

Before the make_empty_dir_inode calls were introduce into proc, sysfs,
and sysctl those directories when stated reported an i_size of 0.
make_empty_dir_inode started reporting an i_size of 2.  At least one
userspace application depended on stat returning i_size of 0.  So
modify make_empty_dir_inode to cause an i_size of 0 to be reported for
these directories.
