With\nCONFIG_STACKPROTECTOR the kernel panics in dm_integrity_check on the\nfirst read.\n\nEnlarge both buffers to hold MAX_TAG_SIZE bytes, as commit b93b6643e9b5\n(\"dm integrity: fix a crash with unusually large tag size\") did for\nintegrity_metadata.\n\nNote that this is not a security bug because the buffer overflow can only\nbe triggered by
