The jbd2-debug file used to be located in /proc/sys/fs/jbd2-debug, but
create_proc_entry() does not do lookups on file names with more that one
directory deep. This causes the entry creation to fail and hence, no proc
file is created. This patch moves the file to /proc/jbd2-degug.
The file could be move to /proc/fs/jbd2/jbd2-debug, but it would require
some minor alterations to the jbd-stats patch.
This is also broken on the original jbd code.

By default, the debugging output will be turned off.
If you select Y here, then you will be able to turn on debugging
- with "echo N > /proc/sys/fs/jbd2-debug", where N is a number between
+ with "echo N > /proc/jbd2-debug", where N is a number between
1 and 5. The higher the number, the more debugging output is
generated. To turn debugging off again, do
