Jeff Layton is working on fully converting ceph. This has been rebased on to the 9p merge in Linus's tree[5] so that it has access to both the 9p conversion to fscache and folios. Changes ======= ver #5: - Got rid of the folio_endio bits again as Willy changed his mind and would rather I inlined the code directly instead. ver #4: - Detached and sent the afs symlink split patch separately. - Handed the 9p netfslibisation patch off to Dominique Martinet. - Added a patch to foliate page_endio(). - Fixed a bug in afs_redirty_page() whereby it didn't set the next page index in the loop and returned too early. - Simplified a check in v9fs_vfs_write_folio_locked()[4]. - Undid a change to afs_symlink_readpage()[4]. - Used offset_in_folio() in afs_write_end()[4]. - Rebased on 9p-folio merge upstream[5]. 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].
