Subject: Re: [PATCH 16/23] Staging: add echo cancelation module
While there are a number of small issues in this code, I personally
would like to first and foremost get a usable interface so I could get a
working echo canceller module into dahdi:
http://svn.digium.com/svn/dahdi/linux/trunk/
http://svn.digium.com/svn/dahdi/linux/trunk/drivers/dahdi/
(Don't preach me that it should be included in mainline. Or if you do,
do it in a different thread, please)
1. echo.h (The interface) needlessly includes the definition of
definition of echo_can_state_t. Anywhere in the interface it is used as
a pointer, including a _create and _destory function.
2. Furthermore, anybody that includes fir.h must also define malloc
first. See echo.c . fir.h is included for the definition of
echo_can_state_t .
3. In that specific environment (dahdi/zaptel) echo_can is not a very
unique prefix. Thus in my provisional change I added oslec_ as a prefix.
I'm not sure how much (3) counts here.
My current working tree is in not in the best place: the debian
(non-existing) package dahdi-linux . See
http://svn.debian.org/viewsvn/pkg-voip?rev=6284&view=rev
I hope that once I get a clear enough interface I can kick out the oslec
subdirectory and move the EC module upstream.

Already done, right? I don't see any _wrapper.c around.
