DTrace updates with new kernel

Recently new kernel patch level became available for Solaris 10 (Sparc). If you do use DTrace I belive you will be interested in this patch. The patch number is 118222-19 and is available for free (no support contract is needed). What's New in -19 revision? - lot of DTrace as you can see - some problems/RFEs are mine :)

update: patch 118844-19 is available for free, this is x86/x64 version of the kernel
