add vminfo.updates to perl kstat module
A recent change for CR 6882903 added the field 'updates' to vminfo_t (defined in sysinfo.h). kstat(1) doesn't show this field when the vminfo kstat is queried, because the perl kstat module hasn't been updated to include this statistic as part of the vminfo kstat.
I believe this just a 1-line change needed to /usr/src/cmd/perl/contrib/Sun/Solaris/Kstat/Kstat.xs
in the save_sysinfo function. I would like to contribute the patch for this myself if possible.
