fs/ntfs: remove redundant variable idx

2022-05-19T21:10:31Z

The variable idx is assigned a value and is never read. The variable is not used and is redundant, remove it. Cleans up clang scan build warning: warning: Although the value stored to 'idx' is used in the enclosing expression, the value is never actually read from 'idx' [deadcode.DeadStores] Link: https://lkml.kernel.org/r/20220517093646.93628-2-colin.i.king@gmail.com Signed-off-by: Colin Ian King Reviewed-by: Anton Altaparmakov Signed-off-by: Andrew Morton

ntfs: Convert ntfs to read_folio

2022-05-09T20:21:46Z

This is a "weak" conversion which converts straight back to using pages. A full conversion should be performed at some point, hopefully by someone familiar with the filesystem. 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)

ntfs: Correct mark_ntfs_record_dirty() folio conversion

2022-04-01T18:40:44Z

We've already done the work of block_dirty_folio() here, leaving only the work that needs to be done by filemap_dirty_folio(). This was a misconversion where I misread __set_page_dirty_nobuffers() as __set_page_dirty_buffers().

Merge tag 'folio-5.18b' of git://git.infradead.org/users/willy/pagecache

2022-03-23T01:26:56Z

Pull filesystem folio updates from Matthew Wilcox: "Primarily this series converts some of the address_space operations to take a folio instead of a page. Notably: - a_ops->is_partially_uptodate() takes a folio instead of a page and changes the type of the 'from' and 'count' arguments to make it obvious they're bytes. - a_ops->invalidatepage() becomes ->invalidate_folio() and has a similar type change. - a_ops->launder_page() becomes ->launder_folio() - a_ops->set_page_dirty() becomes ->dirty_folio() and adds the address_space as an argument.

fs: allocate inode by using alloc_inode_sb()

2022-03-22T22:57:03Z

The inode allocation is supposed to use alloc_inode_sb(), so convert kmem_cache_alloc() of all filesystems to alloc_inode_sb().

ntfs: add sanity check on allocation size

2022-03-22T22:57:00Z

ntfs_read_inode_mount invokes ntfs_malloc_nofs with zero allocation size. It triggers one BUG in the __ntfs_malloc function. Fix this by adding sanity check on ni->attr_list_size.

fs: Convert trivial uses of __set_page_dirty_nobuffers to filemap_dirty_folio
