Subject: [PATCH AUTOSEL 4.14 101/150] hfsplus: update timestamps on truncate()

From: Ernesto A. Fernández <ernesto.mnd.fernandez@...il.com>

[ Upstream commit dc8844aada735890a6de109bef327f5df36a982e ]

The vfs takes care of updating ctime and mtime on ftruncate(), but on
truncate() it must be done by the module.

This patch can be tested with xfstests generic/313.
