Subject: Re: [PATCH 1/5] Move sleeping operations to outside the semaphore.

Quoting Tetsuo Handa (penguin-kernel@...ove.sakura.ne.jp):
> TOMOYO is using rw_semaphore for protecting list elements.

> This patch makes TOMOYO's sleeping operations go outside down_write().

Hi Tetsuo,

another thing making these patches hard for me to review is the lack of
documentation to start with.  There are lists of policy managers, domain
initializers, etc, and I don't know what they are.

Could you flesh out Documentation/tomoyo.txt and/or the variable, struct,
and function definitions under security/tomoyo/ with some explanations?

(A fn comment like
	* tomoyo_update_manager_entry - Add a manager entry.
is not helpful)

That should help me sound less ignorant in the future...

thanks,
-serge
