[Ocfs2-devel] [PATCH]ocfs2-1.2: Add dput for uuid entry.

[Tao Ma <tao.ma@oracle.com>]

Some more information.
The git commit log in the kernel is: 
65c333367b1aea57d58168ad3dc1df27b0227401
http://www.uwsg.indiana.edu/hypermail/linux/kernel/0611.3/0125.html.

In this patch the debugfs_remove is modified(dput is removed), but in 
the latest fs/debugfs/inode.c, dput is still there. So now I really 
don't know whether this function should be modified or not.

Any advice is welcomed.
Thanks.

Regards,
Tao
