…lock() In minix_check_superblock() and minix_fill_super() (fs/minix/inode.c), verify that s_imap_blocks and s_zmap_blocks are large enough to cover s_ninodes + 1 and s_zones, and check the return value of sb_set_blocksize() to prevent out-of-bounds bitmap array reads in minix_count_free_inodes() and minix_new_inode().
