From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andreas Gruenbacher Date: Mon, 5 Jul 2021 20:18:22 +0200 Subject: [Cluster-devel] [PATCH v2 0/2] iomap: small block problems Message-ID: <20210705181824.2174165-1-agruenba@redhat.com> List-Id: To: cluster-devel.redhat.com MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Here are the two fixes that make sure that iop objects get attached to pages eventually (in iomap_writepage_map if not earlier), but not too early (before inline inodes are read). These are the fixes required for making gfs2 filesystems with a block size smaller than the page size work again. As Christoph has pointed out [*], there are several more cases in which we can avoid iop creation. Those improvements are still left to be done.
