Colin Ian King 3993b112da btrfs: avoid null pointer dereference on fs_info when calling btrfs_crit ... There are checks on fs_info in __btrfs_panic to avoid dereferencing a null fs_info, however, there is a call to btrfs_crit that may also dereference a null fs_info. Fix this by adding a check to see if fs_info is null and only print the s_id if fs_info is non-null.
