Justin.

To be clear -- incoming in this case is reads or writes?

Reading from the CIFS share (Windows 7).

Up until 3.0 cifs.ko didn't parallelize writes from a single thread. In
3.0 I added a patchset to increase the allowable wsize and to allow the
kernel to issue writes in parallel.

Ahh, good to know, have not tried writes yet.

Reads still suffer from the same problem however. I'm working on a
patchset that should do the same thing for them, but it requires a
fairly substantial overhaul of the receive codepaths.

Ok, that explains it then, thanks.

One other item, the rsync is currently running, what does mean/what option
would fix it/make the error go away?
