From e8440c1458ba571bc3fac8a6beb53ff604199f5b Mon Sep 17 00:00:00 2001 From: Josh Stone Date: Sun, 13 Jan 2013 19:03:34 +0100 Subject: uprobes: Add exports for module use The original pull message for uprobes (commit 654443e2) noted: This tree includes uprobes support in 'perf probe' - but SystemTap (and other tools) can take advantage of user probe points as well. In order to actually be usable in module-based tools like SystemTap, the interface needs to be exported. This patch first adds the obvious exports for uprobe_register and uprobe_unregister. Then it also adds one for task_user_regset_view, which is necessary to get the correct state of userspace registers.
