8269 dtrace stddev aggregation is normalized incorrectly illumos/illumos-gate@79809f9cf402f130667349b2d4007ecd65d63c6f https://github.com/illumos/illumos-gate/commit/79809f9cf402f130667349b2d4007ecd65d63c6f https://www.illumos.org/issues/8269 It seems that currently normalization of stddev aggregation is done incorrectly. We divide both the sum of values and the sum of their squares by the normalization factor. But we should divide the sum of squares by the normalization factor squared to scale the original values properly. Reviewed by: Bryan Cantrill Approved by: Robert Mustacchi Author: Andriy Gapon

7085 add support for "if" and "else" statements in dtrace

illumos/illumos-gate@c3bd3abd8856e8e75d820f65c58031cd6cbac818 Add syntactic sugar to dtrace: "if" and "else" statements. The sugar is baked down to standard dtrace features by adding additional clauses with the appropriate predicates.
