  "message": "genksyms: track symbol checksum changes\n\nSometimes it is preferable to avoid changes of exported symbol checksums\n(to avoid breaking externally provided modules).  When a checksum change\noccurs, it can be hard to figure out what caused this change: underlying\ntypes may have changed, or additional type information may simply have\nbecome available at the point where a symbol is exported.\n\nAdd a new --reference option to genksyms which allows it to report why\nchecksums change, based on the type information dumps it creates with the\n--dump-types flag.  Genksyms will read in such a dump from a previous run,\nand report which symbols have changed (and why).\n\nThe behavior can be controlled for an entire build as follows: If\nKBUILD_SYMTYPES is set, genksyms uses --dump-types to produce *.symtypes\ndump files.  If any *.symref files exist, those will be used as the\nreference to check against.  If KBUILD_PRESERVE is set, checksum changes\nwill fail the build.\n\nSigned-off-by: Andreas Gruenbacher \u003cagruen@suse.de\u003e\nCc: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Sam Ravnborg \u003csam@ravnborg.org\u003e\n",
