problem of UBI debug info printing

[xiaochuan-xu]

Hello,

No debug message about UBI's WL unit can be found in
/var/log/dmesg file in my 2.6.26-rc5-01191-g23baa5b-dirty kernel. 
I don't why? I need you help. thanks in advance. 

My CONFIG_* is as following:

CONFIG_MTD_UBI_WL_THRESHOLD=4096
CONFIG_MTD_UBI_BEB_RESERVE=1
