This series combines two kmemleak enhancements that were originally submitted
separately but both required rebasing after commit 79c37ae3733e9 ("mm/kmemleak:
fix checksum computation for per-cpu objects").
The first feature introduces a second scan to confirm suspected leaks:
https://lore.kernel.org/all/[email protected]/
The second feature adds a module parameter controlling the minimum number of
consecutive unreferenced scans before a leak is reported, as discussed in:
https://lore.kernel.org/all/[email protected]/
Changes from v1:
Now that commit 79c37ae3733e9 is upstream, the selftest includes an additional
priming phase scan as requested by Catalin.
Additionally, I've factored out the leak-detection conditional into a helper
function to be more digestible for the reader's eye.
This 4-patch series resolves all outstanding kmemleak issues I've been
tracking.
