This patchset does a fairly major cleanup and overhaul of the receive
codepath for cifs. Aside from basic cleanup, there are two main goals:
1) allow the receive codepath to identify the mid before receiving all
of the data for a particular SMB.
...and in turn...
2) add the ability for certain calls to receive their responses into
their into their own set of buffers.
These two changes allow cifs to break the CIFSMaxBufSize barrier for
receives. This patchset just adds the necessary infrastructure to do
the above.
A separate patchset will follow that will overhaul cifs_readpages to use
this infrastructure to allow for a larger rsize.
Jeff Layton (16):
cifs: clean up checkSMB
