Subject: dm thin metadata: remove incorrect close_device on creation error paths
X-Git-Tag: v3.3-rc7~17^2~4
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1f3db25d8be4ac50b897b39609802183ea68a514;p=pandora-kernel.git

dm thin metadata: remove incorrect close_device on creation error paths

The __open_device() error paths in __create_thin() and __create_snap()
incorrectly call __close_device() even if td was not initialized by
__open_device().  Remove this.

Also document __open_device() return values, remove a redundant
td->changed = 1 in __create_thin(), and insert an additional
safeguard against creating an already-existing device.
