Subject: [PATCH] [33/275] Staging: hv: fix sysfs symlink on hv block device

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Ky Srinivasan <ksrinivasan@...ell.com>

commit 268eff909afaca93188d2d14554cbf824f6a0e41 upstream.

The block device does not create the proper symlink in sysfs because we
forgot to set up the gendisk structure properly.  This patch fixes the
issue.
