Ts'o" <tytso@....edu>, Jan Kara <jack@...e.cz>, linux-ext4@...r.kernel.org, linux-xfs@...r.kernel.org, linux-fsdevel@...r.kernel.org Subject: [RFC PATCH V2 10/12] fs/xfs: Fix truncate up From: Ira Weiny <ira.weiny@...el.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.
