Subject: mm: don't opencode filemap_fdatawrite_range in filemap_invalidate_inode
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=99f1aedb299eb1ba4623ae690d4ed7a6276156d6;p=users%2Fhch%2Fmisc.git

mm: don't opencode filemap_fdatawrite_range in filemap_invalidate_inode

Use filemap_fdatawrite_range instead of opencoding the logic using
filemap_fdatawrite_wbc.
