  "message": "update_engine: De-duplicate zlib blocks of squashfs images\n\nHaving duplicate zlib blocks in the squashfs image (e.g. from two\nhard linked files) will cause problems for processing puffin. Recently\nARC++ image introduced two files that where hard linked of each other\nand this caused the squashfs parsing algorithm fail and the ARC++ image\ndoes not get splitted into smaller files. Hence we got massive OOM and\nTimeout problems in the builders. This CL, simpliy removes duplicate\nzlib blocks when constructing the list of such items.\n\nBUG\u003dchromium:955145\nTEST\u003dcros_generate_update_payload --image gs://chromeos-releases/stable-channel/nautilus/11647.154.0/chromeos_11647.154.0_nautilus_recovery_stable-channel_mp-v2.bin --src_image gs://chromeos-releases/stable-channel/nautilus/10575.55.0/chromeos_10575.55.0_nautilus_recovery_stable-channel_mp.bin --output payload.bin\n\nChange-Id: If4eb4731355e1180953a5b327be3a16ff13e6d96\nReviewed-on: https://chromium-review.googlesource.com/1578219\nCommit-Ready: ChromeOS CL Exonerator Bot \u003cchromiumos-cl-exonerator@appspot.gserviceaccount.com\u003e\nTested-by: Amin Hassani \u003cahassani@chromium.org\u003e\nReviewed-by: Sen Jiang \u003csenj@chromium.org\u003e\n(cherry picked from commit 5d185052bd7dea7730777987c2cade748ed4cc46)\n",
