11 .Nd a DTrace provider for dynamic kernel tracing based on function boundaries
18 provider instruments the entry and return of almost every kernel function
21 symbol in the kernel and loaded kernel modules.
34 in the probe description is either the name of the loaded kernel module
36 .Ql kernel
37 for functions compiled into the kernel.

103 31869        fbt     kernel           hammer_time return
109 is a part of the kernel and not a separate loaded module, the
112 .Ql kernel .
160 returns a kernel virtual address.
