This patchset fixes a number of problems with the existing CIFS code. It
eliminates the backreference to the filp from cifsFileInfo, allowing a
cifsFileInfo to outlive the filp that it was generated against.
With that change, most of the closing of a filehandle on the server is
moved to cifsFileInfo_put. cifs_close is then changed to just put the
filehandle instead of trying to wait around for existing users to
finish with it.
With this change, there is some further cleanup that can be done as
well. For instance, there's no real need to continually search for new
filehandles in cifs_writepages now that we hold a reference to one. I'll
hold back on that until I know how this set has been received.
This set is an ordered set and should not be committed out of order. It
should be bisectable. I've tested the resulting set and it seems to work
fine.
