* Add support for the DTrace struct proc and struct thread extendedjb2008-05-181-0/+120
data via ctor and dtor event handlers. The size of the extra data is allocated opaquely and this file contains a function which the dtrace module can call to check that the kernel supports at least the amount of data that it needs. This file is optionally compiled into nthe kernel if the KDTRACE_HOOKS kernel option is defined.
