Subject: dtrace: add dtrace_module_loaded() and dtrace_module_unloaded()
X-Git-Tag: v4.1.12-92~313^2~175
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a2e351f1ff8f75c815608d428f6a1e6933751c92;p=users%2Fjedix%2Flinux-maple.git

dtrace: add dtrace_module_loaded() and dtrace_module_unloaded()

Give the static probes in the kernel image a module name of
  "kernel_builtins" and a module state of LIVE.

Fix an extra-paren typo in dtrace_dev.c.

NOTE:  This is incomplete.  There are a few TBDs and FIXMEs
  in this patch.
