2024-09-03fs/ntfs3: Optimize large writes into sparse fileKonstantin Komarov
Optimized cluster allocation by allocating a large chunk in advance before writing, instead of allocating during the writing process by clusters. Essentially replicates the logic of fallocate.

2024-09-03fs/ntfs3: Check if more than chunk-size bytes are writtenAndrew Ballance
A incorrectly formatted chunk may decompress into more than LZNT_CHUNK_SIZE bytes and a index out of bounds will occur in s_max_off. Signed-off-by: Andrew Ballance <andrewjballance@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>

2024-08-07fs: Convert aops->write_begin to take a folioMatthew Wilcox (Oracle)
Convert all callers from working on a page to working on one page of a folio (support for working on an entire folio can come later). Removes a lot of folio->page->folio conversions.

2024-08-07fs: Convert aops->write_end to take a folioMatthew Wilcox (Oracle)
Most callers have a folio, and most implementations operate on a folio, so remove the conversion from folio->page->folio to fit through this interface.

2024-07-11fs/ntfs3: Fix formatting, change comments, renamingKonstantin Komarov
Huacai Chen: The label end_reply is obviously a typo. It should be "replay" in this context. So rename end_reply to end_replay. Suggested-by: Huacai Chen <chenhuacai@loongson.cn> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
2024-07-11fs/ntfs3: Update log->page_{mask,bits} if log->page_size changedHuacai Chen
If an NTFS file system is mounted to another system with different PAGE_SIZE from the original system, log->page_size will change in log_replay(), but log->page_{mask,bits} don't change correspondingly. This will cause a panic because "u32 bytes = log->page_size - page_off" will get a negative value in the later read_log_page().

2024-07-11fs/ntfs3: Do copy_to_user out of run_lockKonstantin Komarov
In order not to call copy_to_user (from fiemap_fill_next_extent) we allocate memory in the kernel, fill it and copy it to user memory after up_read(run_lock).

2024-06-26ntfs3: Convert attr_wof_frame_info() to use a folioMatthew Wilcox (Oracle)
This involves converting all users of offs_page to offs_folio, but it's worth it because we get rid of a lot of hidden calls to compound_head().

2024-06-26ntfs3: Convert ntfs_get_frame_pages() to use a folioMatthew Wilcox (Oracle)
The function still takes an array of pages, but use a folio internally. This function would deadlock against itself if used with large folios (as it locks each page), so we can be a little sloppy with the conversion back from folio to page for now.
