2022-05-09fs: Convert mpage_readpage to mpage_read_folioMatthew Wilcox (Oracle)
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) <willy@infradead.org>
2022-05-08ntfs3: Remove fsdata parameter from ntfs_extend_initialized_size()Matthew Wilcox (Oracle)
After the last patch, Smatch reports: fs/ntfs3/file.c:168 ntfs_extend_initialized_size() error: uninitialized symbol 'fsdata'. fsdata is indeed unused. This is not new, but Smatch couldn't see it before because calls through pagecache_write_begin()/pagecache_write_end() could theoretically call any implemention of ->write_begin/write_end, some of which do use fsdata. Now that the calls are direct, Smatch can see they're never used. Fix this by simply passing NULL. While ntfs3 does pass this parameter on to generic functions, those generic functions also never dereference the fsdata parameter, so it's unnecessary to pass the address of a real pointer.

Patch series "remove Xen tmem leftovers". Since the removal of the Xen tmem driver in 2019, the cleancache hooks are entirely unused, as are large parts of frontswap. This series against linux-next (with the folio changes included) removes cleancaches, and cuts down frontswap to the bits actually used by zswap.

2021-09-23fs/ntfs3: Remove deprecated mount options nlsKari Argillander
Some discussion has been spoken that this deprecated mount options should be removed before 5.15 lands. This driver is not never seen day light so it was decided that nls mount option has to be removed. We have always possibility to add this if needed. One possible need is example if current ntfs driver will be taken out of kernel and ntfs3 needs to support mount options what it has.
