Subject[RFC PATCH V2 10/12] fs/xfs: Fix truncate up
Date
From: Ira Weiny <ira.weiny@intel.com>

When zeroing the end of a file we must account for bytes contained in
the final page which are past EOF.

Extend the range passed to iomap_zero_range() to reach LLONG_MAX which
will include all bytes of the final page.
