  9p/net: fix possible memory leak in p9_check_errors() (2023-10-27 12:44:13 +0900)

----------------------------------------------------------------
Bunch of small fixes:

- three W=1 warning fixes: the NULL -> "" replacement isn't trivial
but is serialized identically by the protocol layer and has been tested
- one syzbot/KCSAN datarace annotation where we don't care about users
messing with the fd they passed to mount -t 9p
- removing a declaration without implementation
- yet another race fix for trans_fd around connection close:
the 'err' field is also used in potentially racy calls and this
isn't complete, but it's better than what we have.
- and finally a theorical memory leak fix on serialization failure

----------------------------------------------------------------
Dominique Martinet (3):
      9p: v9fs_listxattr: fix %s null argument warning
      9p/net: xen: fix false positive printf format overflow warning
      9p/fs: add MODULE_DESCIPTION
(^ I've just noticed DESCIPTION -> DESCRIPTION typo, but I guess it's
understandable enough and I'd rather not rebase the branch just before
sending the pull request (that last memory leak patch came in late
enough) -- please say if you'd rather I fix it up and I'll resend this)
