Merge tag 'xfs-4.18-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong: "New features this cycle include the ability to relabel mounted filesystems, support for fallocated swapfiles, and using FUA for pure data O_DSYNC directio writes. With this cycle we begin to integrate online filesystem repair and refactor the growfs code in preparation for eventual subvolume support, though the road ahead for both features is quite long. There are also numerous refactorings of the iomap code to remove unnecessary log overhead, to disentangle some of the quota code, and to prepare for buffer head removal in a future upstream kernel. Metadata validation continues to improve, both in the hot path veifiers and the online filesystem check code. I anticipate sending a second pull request in a few days with more metadata validation improvements. This series has been run through a full xfstests run over the weekend and through a quick xfstests run against this morning's master, with no major failures reported. Summary: - Strengthen inode number and structure validation when allocating inodes. - Reduce pointless buffer allocations during cache miss - Use FUA for pure data O_DSYNC directio writes - Various iomap refactorings - Strengthen quota metadata verification to avoid unfixable broken quota - Make AGFL block freeing a deferred operation to avoid blowing out transaction reservations when running complex operations - Get rid of the log item descriptors to reduce log overhead - Fix various reflink bugs where inodes were double-joined to transactions - Don't issue discards when trimming unwritten extents - Refactor incore dquot initialization and retrieval interfaces - Fix some locking problmes in the quota scrub code - Strengthen btree structure checks in scrub code - Rewrite swapfile activation to use iomap and support unwritten extents - Make scrub exit to userspace sooner when corruptions or cross-referencing problems are found - Make scrub invoke the data fork scrubber directly on metadata inodes - Don't do background reclamation of post-eof and cow blocks when the fs is suspended - Fix secondary superblock buffer lifespan hinting - Refactor growfs to use table-dispatched functions instead of long stringy functions - Move growfs code to libxfs - Implement online fs label getting and setting - Introduce online filesystem repair (in a very limited capacity) - Fix unit conversion problems in the realtime freemap iteration functions - Various refactorings and cleanups in preparation to remove buffer heads in a future release - Reimplement the old bmap call with iomap - Remove direct buffer head accesses from seek hole/data - Various bug fixes" * tag 'xfs-4.18-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (121 commits) fs: use ->is_partially_uptodate in page_cache_seek_hole_data fs: remove the buffer_unwritten check in page_seek_hole_data fs: move page_cache_seek_hole_data to iomap.c xfs: use iomap_bmap iomap: add an iomap-based bmap implementation iomap: add a iomap_sector helper iomap: use __bio_add_page in iomap_dio_zero iomap: move IOMAP_F_BOUNDARY to gfs2 iomap: fix the comment describing IOMAP_NOWAIT iomap: inline data should be an iomap type, not a flag mm: split ->readpages calls to avoid non-contiguous pages lists mm: return an unsigned int from __do_page_cache_readahead mm: give the 'ret' variable a better name __do_page_cache_readahead block: add a lower-level bio_add_page interface xfs: fix error handling in xfs_refcount_insert() xfs: fix xfs_rtalloc_rec units xfs: strengthen rtalloc query range checks xfs: xfs_rtbuf_get should check the bmapi_read results xfs: xfs_rtword_t should be unsigned, not signed dax: change bdev_dax_supported() to support boolean returns ...

block: add a lower-level bio_add_page interface

2018-06-02T01:37:32Z

For the upcoming removal of buffer heads in XFS we need to keep track of the number of outstanding writeback requests per page. For this we need to know if bio_add_page merged a region with the previous bvec or not. Instead of adding additional arguments this refactors bio_add_page to be implemented using three lower level helpers which users like XFS can use directly if they care about the merge decisions.

block: Split out bio_list_copy_data()

2018-05-14T19:16:10Z

Found a bug (with ASAN) where we were passing a bio to bio_copy_data() with bi_next not NULL, when it should have been - a driver had left bi_next set to something after calling bio_endio(). Since the normal case is only copying single bios, split out bio_list_copy_data() to avoid more bugs like this in the future. Signed-off-by: Kent Overstreet Signed-off-by: Jens Axboe
