These patches are carefully plucked from the THP series. I would like them to hit 5.10 to make the THP patchset merge easier. Some of these are just generic improvements that make sense on their own terms, but the overall intent is to support THPs in iomap. v2: - Move the call to flush_dcache_page (Christoph) - Clarify comments (Darrick) - Rename read_count to read_bytes_pending (Christoph) - Rename write_count to write_bytes_pending (Christoph) - Restructure iomap_readpage_actor() (Christoph) - Change return type of the zeroing functions from loff_t to s64 Matthew Wilcox (Oracle) (9): iomap: Fix misplaced page flushing fs: Introduce i_blocks_per_page iomap: Use kzalloc to allocate iomap_page iomap: Use bitmap ops to set uptodate bits iomap: Support arbitrarily many blocks per page iomap: Convert read_count to read_bytes_pending iomap: Convert write_count to write_bytes_pending iomap: Convert iomap_write_end types iomap: Change calling convention for zeroing fs/dax.c | 13 ++- fs/iomap/buffered-io.c | 173 +++++++++++++++++----------------------- fs/jfs/jfs_metapage.c | 2 +- fs/xfs/xfs_aops.c | 2 +- include/linux/dax.h | 3 +- include/linux/pagemap.h | 16 ++++ 6 files changed, 96 insertions(+), 113 deletions(-) -- 2.28.0
