9p: Use a slab for allocating requests

2018-08-29T04:39:57+00:00

Replace the custom batch allocation with a slab.  Use an IDR to store
pointers to the active requests instead of an array.  We don't try to
handle P9_NOTAG specially; the IDR will happily shrink all the way back
once the TVERSION call has completed.

The ret is modified after initalization, so just remove it and
return 0.

9p: Reduce object size with CONFIG_NET_9P_DEBUG

2012-01-05T16:51:44+00:00

Reduce object size by deduplicating formats.

Use vsprintf extension %pV.
Rename P9_DPRINTK uses to p9_debug, align arguments.
Add function for _p9_debug and macro to add __func__.
Add missing "\n"s to p9_debug uses.
Remove embedded function names as p9_debug adds it.
Remove P9_EPRINTK macro and convert use to pr_.
Add and use pr_fmt and pr_.

net/9p: Change linuxdoc names to match functions.

2011-05-25T13:46:37+00:00

As on Jeopardy, my question is in the form of a patch:  Does this have
some special meaning, or is it an accident?  (I looked at other
filesystems but they didn't bother having doc entries for their
init/exit function that I could find.)

9p: consolidate transport structure

2008-10-17T16:04:41+00:00

Right now there is a transport module structure which provides per-transport
type functions and data and a transport structure which contains per-instance
public data as well as function pointers to instance specific functions.

This patch moves public transport visible instance data to the client
structure (which in some cases had duplicate data) and consolidates the
functions into the transport module structure.

9p: implement proper trans module refcounting and unregistration

2008-09-24T21:22:23+00:00

9p trans modules aren't refcounted nor were they unregistered
properly.  Fix it.

* Add 9p_trans_module->owner and reference the module on each trans
  instance creation and put it on destruction.

* Protect v9fs_trans_list with a spinlock.  This isn't strictly
  necessary as the list is manipulated only during module loading /
  unloading but it's a good idea to make the API safe.

* Unregister trans modules when the corresponding module is being
  unloaded.

* While at it, kill unnecessary EXPORT_SYMBOL on p9_trans_fd_init().

9p: fix error path during early mount

2008-05-15T00:23:27+00:00

There was some cleanup issues during early mount which would trigger
a kernel bug for certain types of failure.  This patch reorganizes the
cleanup to get rid of the bad behavior.

This also merges the 9pnet and 9pnet_fd modules for the purpose of
configuration and initialization.  Keeping the fd transport separate
from the core 9pnet code seemed like a good idea at the time, but in
practice has caused more harm and confusion than good.
