For several MoviNAND, there are some known issue with secure option.
For these specific MoviNAND device, we skip secure option.
You could refer this discussion in XDA developers.
I was configuring a kernel build and stumbled across some options, which
default to [n], but the help says If unsure, say Y.
Also the other way round defaulting to [y],
but the help saying If unsure, say N.
So now I am really unsure, what to pick.
Here is a list of options, which I found with a

Dave,
This batch of fixes is intended for 3.6.
Alexey Khoroshilov provides a potential memory leak in rndis_wlan.
Bob Copeland gives us an ath5k fix for a lockdep problem.
Dan Carpenter fixes a signedness mismatch in at76c50x.

This function does not exist. So what?
It makes the workqueue users messy. It's difficult to get completely
correct and subtle errors are difficult to

Mike,
Previous pseudo code was not correct.
More precisely, it is as follows.
But, we still need to alloc memory dynamically in the part of Save information
about new entry
because a workqueue can't know how many new entries in advance.
