Subject: reiserfs: fix handling of device names with /'s in them
From: Jeff Mahoney <jeffm@xxxxxxxx>
On systems with block devices containing a slash (virtual dasd, cciss,
etc), reiserfs will fail to initialize /proc/fs/reiserfs/<dev> due to it
being interpreted as a subdirectory. The generic block device code changes
the / to ! for use in the sysfs tree. This patch uses that convention.
Tested by making dm devices use dm/<number> rather than dm-<number>
