fs: remove the NULL get_block case in mpage_writepages

2022-08-02T16:34:04Z

No one calls mpage_writepages with a NULL get_block paramter, so remove support for that case. Signed-off-by: Christoph Hellwig Reviewed-by: Jan Kara Signed-off-by: Matthew Wilcox (Oracle)

fs: don't call ->writepage from __mpage_writepage

2022-08-02T16:34:04Z

All callers of mpage_writepage use block_write_full_page as their ->writepage implementation when called from mpage_writepages (although for ntfs3 this is obsfucated a bit). Just call block_write_full_page directly instead of going through the ->writepage indirection. Signed-off-by: Christoph Hellwig Reviewed-by: Jan Kara Signed-off-by: Matthew Wilcox (Oracle)

fs: remove the nobh helpers

2022-08-02T16:34:04Z

All callers are gone, so remove the now dead code. Signed-off-by: Christoph Hellwig Reviewed-by: Jan Kara Signed-off-by: Matthew Wilcox (Oracle)

fs/mpage: Use the new blk_opf_t type

2022-07-14T18:14:32Z

Improve static type checking by using the new blk_opf_t type for the combination of a block layer request with block layer request flags.

mpage: Convert do_mpage_readpage() to use a folio

2022-06-29T12:51:05Z

Pass in a folio from mpage_readahead(). Also convert map_buffer_to_page() to map_buffer_to_folio(). There's still no support for large folios here; there are numerous places which depend on the folio being PAGE_SIZE. The VM_BUG_ON prevents anyone from thinking that it will work.

fs: Change try_to_free_buffers() to take a folio

2022-05-10T03:12:34Z

All but two of the callers already have a folio; pass a folio into try_to_free_buffers(). This removes the last user of cancel_dirty_page() so remove that wrapper function too. Signed-off-by: Matthew Wilcox (Oracle) Reviewed-by: Jeff Layton

fs: Convert mpage_readpage to mpage_read_folio

2022-05-09T20:21:44Z

mpage_readpage still works in terms of pages, and has not been audited for correctness with large folios, so include an assertion that the filesystem is not passing it large folios. Convert all the filesystems to call mpage_read_folio() instead of mpage_readpage(). Signed-off-by: Matthew Wilcox (Oracle)

fs: Convert block_read_full_page() to block_read_full_folio()

2022-05-09T20:21:44Z

This function is NOT converted to handle large folios, so include an assert that the filesystem isn't passing one in. Otherwise, use the folio functions instead of the page functions, where they exist. Convert all filesystems which use block_read_full_page(). Signed-off-by: Matthew Wilcox (Oracle)
