Subject: [PATCHSET] 9p: clean up a bit and use single poller for trans_fd


This patchset cleans up 9p and 9p-trans_fd a bit and convert trans_fd
to use single poller instead of poll of pollers and contains the
following six patches.

  0001-9p-implement-proper-trans-module-refcounting-and-un.patch
  0002-9p-trans_fd-fix-trans_fd-p9_conn_destroy.patch
  0003-9p-trans_fd-clean-up-p9_conn_create.patch
  0004-9p-trans_fd-don-t-do-fs-segment-mangling-in-p9_fd_p.patch
  0005-9p-trans_fd-fix-and-clean-up-module-init-exit-paths.patch
  0006-9p-trans_fd-use-single-poller.patch

0001 fixes trans module registration and unregistration.  0002-0005
fix a few bugs in and clean up trans_fd.  0006 converts trans_fd to
use single poller instead of pool of pollers.

Although this patchset fixes a few problem cases but there still are
other synchronization issues in trans_fd.  Most notably, a request
which is being flushed can be freed before r/w works are done with
them.  What's necessary is probably flushing r/w works before actually
destroying the request from flush.  Well, I guess that's for another
day.

This patchset is on top of the current linus#master (399d7f6b) and the
combined diffstat follows.
