users to guarantee that the output of DTrace scripts will be time-ordered. This option is enabled by adding the line #pragma D option temporal to the beginning of a script, or by adding '-x temporal' to the arguments of dtrace(1). This change fixes a bug in the original port of the temporal option. This bug was causing some assertions to fail, so they had been disabled; in this revision the assertions are working properly and are enabled. The DTrace version number has been bumped from 1.9.0 to 1.9.1 to reflect the language change that's being introduced. This change corresponds to part of illumos-gate commit e5803b76927480: 3021 option for time-ordered output from dtrace(1M) Reviewed by: pfg Obtained from: illumos MFC after: 1 month
