[Synce-devel] kernel support for wm5

[Farkas Levente]

hi,
i see that kernel support for rndis_host still not 100% (although just
one liner). when we can expect full kernel support? in which kernel
version? if it's so simple why not included in the upstream kernel? it'd
be much easier for everybody who don't like to compile kernel all the
time, simple use their distro's kernel update process and only user
space components should have to upgraded.
just my 2c.

All patches have been submitted upstream, but the maintainer has (thus far)
backed off on applying this last one. Remember the rndis_host module is not
*only* for use by us, so when applying changes he must be sure that any
change is sane for the module's other uses as well. I suspect that is his
reason, but I can't be sure.

I would also like very much not to have to patch the kernel each time I
upgrade it - you are not the only one.

who is the upstream maintainer and what was his reason not to included it?

I'll defer to either jonnylamb or Ole Andre to answer this in more detail.
Basically the WM5 devices require very large USB packets, and thats what this
remaining patch does. I don't recall (either that or I never knew) what his
reason for not including it was, but I suspect it was either that he didn't
fully understand the problem or that he was forseeing compatibility problems
with other devices or uses of that driver. If jonnylamb or Ole Andre want to
fill in more details (or fix up the explanation), feel free...

You can find the maintainer in the git logs for this file at kernel.org.
