Alexei Filippov ac8a5bd24c jfs: validate max amount of blocks before allocation. ... [ Upstream commit 0225e10972 ] The lack of checking bmp->db_max_freebud in extBalloc() can lead to shift out of bounds, so this patch prevents undefined behavior, because bmp->db_max_freebud == -1 only if there is no free space.
