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

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

aha, sorry for the noise. :(

dput is added in the next commit 29a7f3ada7fea5510504c5359c3f70d109aeb055.
http://www.uwsg.indiana.edu/hypermail/linux/kernel/0611.3/0126.html

So here my question is should we patch these 2 patches into our 
ocfs2-1.2 or just the 1st one?

Regards,
Tao
