Hi Anton,

FYI, coccinelle warns about

fs/ntfs/super.c:2717:1-14: alloc with no test, possible model on line 2718

vim +2717 fs/ntfs/super.c
  2714		sb->s_flags |= MS_RDONLY;
  2715	#endif /* ! NTFS_RW */
  2716		/* Allocate a new ntfs_volume and place it in sb->s_fs_info. */
> 2717		sb->s_fs_info = kmalloc(sizeof(ntfs_volume), GFP_NOFS);
  2718		vol = NTFS_SB(sb);
  2719		if (!vol) {
  2720			if (!silent)
