Subject: mm: don't opencode filemap_fdatawrite_range in filemap_invalidate_inode
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a21134b5d6cb5e9e11fd170c48eeba6f82f1b2a0;p=thirdparty%2Flinux.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.
