Hi Linus, Please pull this series containing all the new iomap code for 5.4. The biggest change here is porting some of XFS' writeback code to iomap so that we can share it with other filesystems; and making some adjustments to the iomap directio code in preparation for other filesystems starting to use it. In 5.5 we hope to finish converting XFS to iomap and to start converting a few other filesystems. The branch merges cleanly against this morning's HEAD and survived a couple of weeks' worth of xfstests. The merge was completely straightforward, so please let me know if you run into anything weird. --D The following changes since commit 609488bc979f99f805f34e9a32c1e3b71179d10b: Linux 5.3-rc2 (2019-07-28 12:47:02 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git tags/iomap-5.4-merge-4 for you to fetch changes up to 68494b8e248fe8a7b6e9f88edd9a87661760ddb9: iomap: move the iomap_dio_rw ->end_io callback into a structure (2019-09-03 08:28:22 -0700) ---------------------------------------------------------------- New code for 5.4: - Port the XFS writeback code to iomap with the eventual goal of converting XFS to use it. - Clean up a few odds and ends in xfs writeback and convert the xfs ioend code to use list_pop and friends. - Report both io errors and short io results to the directio endio handler. - Allow directio callers to pass an ops structure to iomap_dio_rw. ---------------------------------------------------------------- Andreas Gruenbacher (1): iomap: Fix trivial typo Christoph Hellwig (9): list.h: add list_pop and list_pop_entry helpers iomap: copy the xfs writeback code to iomap.c iomap: add tracing for the address space operations iomap: warn on inline maps in iomap_writepage_map xfs: set IOMAP_F_NEW more carefully iomap: zero newly allocated mapped blocks xfs: initialize iomap->flags in xfs_bmbt_to_iomap xfs: refactor the ioend merging code iomap: move the iomap_dio_rw ->end_io callback into a structure Matthew Bobrowski (1): iomap: split size and error for iomap_dio_rw ->end_io Randy Dunlap (1): tracing: fix iomap.h build warnings fs/iomap/buffered-io.c | 575 ++++++++++++++++++++++++++++++++++++++++++- fs/iomap/direct-io.c | 24 +- fs/xfs/xfs_aops.c | 70 +++--- fs/xfs/xfs_file.c | 14 +- fs/xfs/xfs_iomap.c | 35 ++- fs/xfs/xfs_iomap.h | 2 +- fs/xfs/xfs_pnfs.c | 2 +- include/linux/iomap.h | 53 +++- include/linux/list.h | 33 +++ include/trace/events/iomap.h | 87 +++++++ 10 files changed, 824 insertions(+), 71 deletions(-) create mode 100644 include/trace/events/iomap.h
