Browse source 
Added:
     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
 	a fall-through between switch labels
 	a delayed-allocation (delalloc) support
 
 Fixed:
     check return value of indx_find to avoid infinite loop
 	initialize new folios before use
 	an infinite loop in attr_load_runs_range on inconsistent metadata
 	an infinite loop triggered by zero-sized ATTR_LIST
 	ntfs_mount_options leak in ntfs_fill_super()
 	a deadlock in ni_read_folio_cmpr
 	a 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()
 	a slab-out-of-bounds read in DeleteIndexEntryRoot
 
 Changed:
     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
