  1. fs/9p: Add fid before dentry instantiation 

    d_instantiate marks the dentry positive. So a parallel lookup and mkdir of
the directory can find dentry that doesn't have fid attached. This can result
in both the code path doing v9fs_fid_add which results in v9fs_dentry leak.

  2. fs/9p: Don't update file type when updating file attributes 

    We should only update attributes that we can change on stat2inode.
Also do file type initialization in v9fs_init_inode.

  5. fs/9p: Always ask new inode in lookup for cache mode disabled 

    This make sure we don't end up reusing the unlinked inode object.
The ideal way is to use inode i_generation. But i_generation is
not available in userspace always.
