inode instead of a vfs inode as parameter.
- Fix the definition of the CHKD ntfs record magic. It had an off by
two error causing it to be CHKB instead of CHKD.
+ - Fix a stupid bug in __ntfs_bitmap_set_bits_in_run() which caused the
+ count to become negative and hence we had a wild memset() scribbling
+ all over the system's ram.
2.1.23 - Implement extension of resident files and make writing safe as well as
many bug fixes, cleanups, and enhancements...
