Subject: [PATCH 4.4 58/90] ufs_extend_tail(): fix the braino in calling conventions of ufs_new_fragments()

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Al Viro <viro@...iv.linux.org.uk>

commit 940ef1a0ed939c2ca029fca715e25e7778ce1e34 upstream.

... and it really needs splitting into "new" and "extend" cases, but that's for
later
