- Use MAX_BUF_PER_PAGE instead of variable sized array allocation for
better code generation and one less sparse warning in fs/ntfs/aops.c.
- Remove spurious void pointer casts from fs/ntfs/. (Pekka Enberg)
- Use C99 style structure initialization after memory allocation where
possible (fs/ntfs/{attrib.c,index.c,super.c}). Thanks to Al Viro and
Pekka Enberg.
2.1.22 - Many bug and race fixes and error handling improvements.
