GFS2: Fix cache coherency between truncate and O_DIRECT read
If a page was partially zeroed as the result of a truncate, then it was not being correctly marked dirty. This resulted in the deleted data reappearing if the file was read back via direct I/O. Reported-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
