[PATCH v2 0/5] uprobes: misc cleanups/simplifications

Posted by Oleg Nesterov 1 year, 6 months ago

Peter, I don't think these changes can really complicate your ongoing work.
But again, if you are going to send the next version "soon" I can rebase
these cleanups on top of it.

Andrii, I dared to preserve your acks, all the changes are simple.

Changes since v1:

	- update the comment in register_for_each_vma()
	- remove the now unused "struct path *" arg from bpf_uprobe_unregister()
	- forward-declare struct uprobe in include/linux/uprobes.h
	- kernel-doc fixes/updates
	- fix use-after free in uprobe_unregister(). See "TODO:" in 5/5.

Oleg.
