Subject: [PATCH v5 00/18] Refactor generic_file_buffered_read
Date: Fri, 22 Jan 2021 16:01:22 +0000 [thread overview]
Message-ID: <20210122160140.223228-1-willy@infradead.org> (raw)
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.
v5:
- Rebase on next-20210122 (new conflict due to typo fix)
- Folded in Reviewed-bys
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)
