[DTrace-devel] [PATCH 05/19] Add flag to dt_pid_create_probes()

[Eugene Loh]

Okay.  I'll patch a v2, whose Subject will now be:  "Split 
dt_pid_create_probes() into pid and USDT functions".  There are 
cascading impacts on some other following patches.  So, I'll post new 
versions of those patches as well.
