This is a combination of Christoph's work to refactor generic_file_buffered_read() and some of my large-page support which was disrupted by Kent's refactoring of generic_file_buffered_read. v4: - Rebase on next-20210120 - Fix compilation error with pagevec_init & reinit - Simplify filemap_range_uptodate() by passing pos instead of iocb v3: - Fixed missing put_page for readahead with IOCB_NOIO (hch) - Fixed commit message for lock_page_for_iocb (nborisov) v2: - Added pagevec conversion upfront and rebased other patches on top of it (me) - Limit page search by max pgoff_t rather than by number of pages (me) - Renamed mapping_get_read_thps() to filemap_get_read_batch() (hch/me) - Added doc for filemap_get_read_batch() (hch/me) - Removed 'first' parameter from filemap_update_page() (me) - Folded "Remove parameters from filemap_update_page()" into an earlier patch (hch) - Restructured filemap_update_page() error handling flow (hch/me) - Pass the pagevec to filemap_create_page() (hch) - Renamed 'find_page' label to 'retry' (hch) - Explicitly check for AOP_TRUNCATED_PAGE instead of assuming err > 0 means retry (hch) - Move mark_page_accessed() and handling of i_size into main copy loop (me) Christoph Hellwig (2): mm/filemap: Rename generic_file_buffered_read to filemap_read mm/filemap: Simplify generic_file_read_iter Matthew Wilcox (Oracle) (16): mm/filemap: Rename generic_file_buffered_read subfunctions mm/filemap: Remove dynamically allocated array from filemap_read mm/filemap: Convert filemap_get_pages to take a pagevec mm/filemap: Use head pages in generic_file_buffered_read mm/filemap: Pass a sleep state to put_and_wait_on_page_locked mm/filemap: Support readpage splitting a page mm/filemap: Inline __wait_on_page_locked_async into caller mm/filemap: Don't call ->readpage if IOCB_WAITQ is set mm/filemap: Change filemap_read_page calling conventions mm/filemap: Change filemap_create_page calling conventions mm/filemap: Convert filemap_update_page to return an errno mm/filemap: Move the iocb checks into filemap_update_page mm/filemap: Add filemap_range_uptodate mm/filemap: Split filemap_readahead out of filemap_get_pages mm/filemap: Restructure filemap_get_pages mm/filemap: Don't relock the page after calling readpage fs/btrfs/file.c | 2 +- include/linux/fs.h | 4 +- include/linux/pagemap.h | 3 +- mm/filemap.c | 565 ++++++++++++++++++---------------------- mm/huge_memory.c | 4 +- mm/migrate.c | 4 +- 6 files changed, 267 insertions(+), 315 deletions(-) -- 2.29.2
