ANDROID: sdcardfs: fix potential crash when reserved_mb is not zero sdcardfs_mkdir() calls check_min_free_space(). When reserved_mb is not zero, a negative dentry will be passed to ext4_statfs() at last and ext4_statfs() will crash. The parent dentry is positive. So we use the parent dentry to check free space.
