- * Having the wrong rootdevice listed in mtab is slightly inconvenient.
- * Try to guess what it could be...
- * In case /proc/cmdline exists, and has the format
- *	stuff root=R more stuff...
- * and we think we understand the number R, decode it as a root device.
- *
- * Another possibility:
- * Erik Andersen writes:
- *  I did a similar find_real_root_device_name() in busybox some time back.  
- *  Basically, do a stat("/", &rootstat) then walk /dev stat'ing each file
- *  and if (statbuf.st_rdev == rootstat.st_rdev) then you have a match.
- *  Works fine.
