NTFS: - In fs/ntfs/compress.c, use i_size_read() at the start and then use the
cached value everywhere. Cache the initialized_size in the same way
and protect the critical region where the two sizes are read using the
new size_lock of the ntfs inode.
- Add the new size_lock to the ntfs_inode structure (fs/ntfs/inode.h)
and initialize it (fs/ntfs/inode.c).
