[PATCH 4.14 116/211] hfs: update timestamp on truncate()

[Greg Kroah-Hartman]

From: Ernesto A. FernÃndez <ernesto.mnd.fernandez@xxxxxxxxx>

[ Upstream commit 8cd3cb5061730af085a3f9890a3352f162b4e20c ]

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