  "message": "cos_kernel_args: fix bzimage packing\n\nUse padding to ensure that the compressed bzImage payload doesn\u0027t change\nsize. It\u0027s important that the output bzImage is smaller than the input\nbzImage in order for padding to work; we can guarantee this by making\nthe initial command line value as high entropy as possible (this will be\nset in CONFIG_CMDLINE at kernel compile time). Also use the gzip tool\nfor compression/decompression, because the Go stdlib both doesn\u0027t fully\nimplement the gzip spec and inflates the size of the compressed data.\n\nBUG\u003db/465210631\n\nChange-Id: Ifbf700e76c144a3cef98c33596814ca5683f2631\nReviewed-on: https://cos-review.googlesource.com/c/cos/tools/+/143583\nTested-by: Robert Kolchmeyer \u003crkolchmeyer@google.com\u003e\nReviewed-by: He Gao \u003chegao@google.com\u003e\nCloud-Build: GCB Service account \u003c228075978874@cloudbuild.gserviceaccount.com\u003e\n",
