Here's a set of miscellaneous fix patches. There are a couple of points of note:
(1) There is one non-fix patch that adjusts the call ref tracking tracepoint to make kernel API-held refs on calls more obvious. This is a prerequisite for the patch that fixes prealloc refcounting. (2) The final patch alters how jumbo packets that partially exceed the receive window are handled. Previously, space was being left in the Rx buffer for them, but this significantly hurts performance as the Rx window can't be increased to match the OpenAFS Tx window size. Instead, the excess subpackets are discarded and an EXCEEDS_WINDOW ACK is generated for the first. To avoid the problem of someone trying to run the kernel out of space by feeding the kernel a series of overlapping maximal jumbo packets, we stop allowing jumbo packets on a call if we encounter more than three jumbo packets with duplicate or excessive subpackets.
