[DTrace-devel] [PATCH 2/4] uprobe: remove unnecessary enable_*() functions

[Eugene Loh]

Reviewed-by: Eugene Loh <eugene.loh at oracle.com>

although, admittedly, I wouldn't mind, e.g., a one-sentence commit 
message like:

     This clean up should have been part of caf431aed4 ("Remove the 
is-enabled provider").

(Oops.  My fault.)
