Subject[PATCH 4.14 124/165] fuse: Add missed unlock_page() to fuse_readpages_fill()
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Kirill Tkhai <ktkhai@virtuozzo.com>

commit 109728ccc5933151c68d1106e4065478a487a323 upstream.

The above error path returns with page unlocked, so this place seems also
to behave the same.

Fixes: f8dbdf81821b ("fuse: rework fuse_readpages()")
