Thank you!
Hi Linus, Please pull this new iomap code for 5.15-rc1. The most notable externally visible change for this cycle is the addition of support for reads to inline tail fragments of files, which was requested by the erofs developers; and a correction for a kernel memory corruption bug if the sysadmin tries to activate a swapfile with more pages than the swapfile header suggests. We also now report writeback completion errors to the file mapping correctly, instead of munging all errors into EIO. Internally, the bulk of the changes are Christoph's patchset to reduce the indirect function call count by a third to a half by converting iomap iteration from a loop pattern to a generator/consumer pattern. As an added bonus, fsdax no longer open-codes iomap apply loops. The branch merges cleanly with upstream as of a few minutes ago and has been soaking in for-next for a couple of weeks without complaints. Please let me know if there are any problems. --D The following changes since commit c500bee1c5b2f1d59b1081ac879d73268ab0ff17: Linux 5.14-rc4 (2021-08-01 17:04:17 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git tags/iomap-5.15-merge-4 for you to fetch changes up to 03b8df8d43ecc3c5724e6bfb80bc0b9ea2aa2612: iomap: standardize tracepoint formatting and storage (2021-08-26 09:18:53 -0700) ---------------------------------------------------------------- New code for 5.15: - Simplify the bio_end_page usage in the buffered IO code. - Support reading inline data at nonzero offsets for erofs. - Fix some typos and bad grammar. - Convert kmap_atomic usage in the inline data read path. - Add some extra inline data input checking. - Fix a memory corruption bug stemming from iomap_swapfile_activate trying to activate more pages than mm was expecting. - Pass errnos through the page writeback code so that writeback errors are reported correctly instead of being munged to EIO. - Replace iomap_apply with a open-coded iterator loops to reduce the number of indirect calls by a third to a half. - Refactor the fsdax code to use iomap iterators instead of the open-coded iomap_apply code that it had before. - Format file range iomap tracepoint data in hexadecimal and standardize the names used in the pretty-print string. ---------------------------------------------------------------- Andreas Gruenbacher (1): iomap: Fix some typos and bad grammar Christoph Hellwig (30): iomap: simplify iomap_readpage_actor iomap: simplify iomap_add_to_ioend iomap: fix a trivial comment typo in trace.h iomap: remove the iomap arguments to ->page_{prepare,done} iomap: mark the iomap argument to iomap_sector const iomap: mark the iomap argument to iomap_inline_data const iomap: mark the iomap argument to iomap_inline_data_valid const fs: mark the iomap argument to __block_write_begin_int const fsdax: mark the iomap argument to dax_iomap_sector as const iomap: mark the iomap argument to iomap_read_inline_data const iomap: mark the iomap argument to iomap_read_page_sync const iomap: fix the iomap_readpage_actor return value for inline data iomap: add the new iomap_iter model iomap: switch readahead and readpage to use iomap_iter iomap: switch iomap_file_buffered_write to use iomap_iter iomap: switch iomap_file_unshare to use iomap_iter iomap: switch iomap_zero_range to use iomap_iter iomap: switch iomap_page_mkwrite to use iomap_iter iomap: switch __iomap_dio_rw to use iomap_iter iomap: switch iomap_fiemap to use iomap_iter iomap: switch iomap_bmap to use iomap_iter iomap: switch iomap_seek_hole to use iomap_iter iomap: switch iomap_seek_data to use iomap_iter iomap: switch iomap_swapfile_activate to use iomap_iter fsdax: switch dax_iomap_rw to use iomap_iter iomap: remove iomap_apply iomap: pass an iomap_iter to various buffered I/O helpers iomap: rework unshare flag fsdax: switch the fault handlers to use iomap_iter iomap: constify iomap_iter_srcmap Darrick J.
