The patch titled
tracehook: exit
has been removed from the -mm tree. Its filename was
tracehook-exit.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: tracehook: exit
From: Roland McGrath <roland@xxxxxxxxxx>
This moves the PTRACE_EVENT_EXIT tracing into a tracehook.h inline,
tracehook_report_exec(). The change has no effect, just clean-up.
