Here's a set of patches to convert netfs, 9p and afs to use folios and to provide sufficient conversion for ceph that it can continue to use the netfs library. Jeff Layton is working on fully converting ceph. This also contains a patch to split afs symlink readpage from afs file readpage to aid with foliation and a patch to convert 9p to netfslib to reduce the amount of foliation needed there. Changes ======= ver #3: - Rebased on upstream as folios have been pulled. - Imported a patch to convert 9p to netfslib from my fscache-remove-old-api branch[3]. - Foliated netfslib. ver #2: - Reorder the patches to put both non-folio afs patches to the front. - Use page_offset() rather than manual calculation[1]. - Fix folio_inode() to directly access the inode[2].
