Pull ntfs3 updates from Konstantin Komarov: "New code: - improve readahead for bitmap initialization and large directory scans - fsync files by syncing parent inodes - drop of preallocated clusters for sparse and compressed files - zero-fill folios beyond i_valid in ntfs_read_folio() - implement llseek SEEK_DATA/SEEK_HOLE by scanning data runs - implement iomap-based file operations - allow explicit boolean acl/prealloc mount options - fall-through between switch labels - delayed-allocation (delalloc) support Fixes: - check return value of indx_find to avoid infinite loop - initialize new folios before use - infinite loop in attr_load_runs_range on inconsistent metadata - infinite loop triggered by zero-sized ATTR_LIST - ntfs_mount_options leak in ntfs_fill_super() - deadlock in ni_read_folio_cmpr - circular locking dependency in run_unpack_ex - prevent infinite loops caused by the next valid being the same - restore NULL folio initialization in ntfs_writepages() - slab-out-of-bounds read in DeleteIndexEntryRoot Updates: - allow readdir() to finish after directory mutations without rewinddir() - handle attr_set_size() errors when truncating files - make ntfs_writeback_ops static - refactor duplicate kmemdup pattern in do_action() - avoid calling run_get_entry() when run == NULL in ntfs_read_run_nb_ra() Replaced: - use wait_on_buffer() directly - rename ni_readpage_cmpr into ni_read_folio_cmpr" * tag 'ntfs3_for_7.0' of https://github.com/Paragon-Software-Group/linux-ntfs3: (26 commits) fs/ntfs3: add delayed-allocation (delalloc) support fs/ntfs3: avoid calling run_get_entry() when run == NULL in ntfs_read_run_nb_ra() fs/ntfs3: add fall-through between switch labels fs/ntfs3: allow explicit boolean acl/prealloc mount options fs/ntfs3: Fix slab-out-of-bounds read in DeleteIndexEntryRoot ntfs3: Restore NULL folio initialization in ntfs_writepages() ntfs3: Refactor duplicate kmemdup pattern in do_action() fs/ntfs3: prevent infinite loops caused by the next valid being the same fs/ntfs3: make ntfs_writeback_ops static ntfs3: fix circular locking dependency in run_unpack_ex fs/ntfs3: implement iomap-based file operations fs/ntfs3: fix deadlock in ni_read_folio_cmpr fs/ntfs3: implement llseek SEEK_DATA/SEEK_HOLE by scanning data runs fs/ntfs3: zero-fill folios beyond i_valid in ntfs_read_folio() fs/ntfs3: handle attr_set_size() errors when truncating files fs/ntfs3: drop preallocated clusters for sparse and compressed files fs/ntfs3: fsync files by syncing parent inodes fs/ntfs3: fix ntfs_mount_options leak in ntfs_fill_super() fs/ntfs3: allow readdir() to finish after directory mutations without rewinddir() fs/ntfs3: improve readahead for bitmap initialization and large directory scans ...
