In an ideal world your kmemleak output will be small, when its not (usually during initial bootup) you can use the clear command to ingore previously reported and unreferenced kmemleak objects. We do this by painting all currently reported unreferenced objects grey. We paint them grey instead of black to allow future scans on the same objects as such objects could still potentially reference newly allocated objects in the future. To test a critical section on demand with a clean /sys/kernel/debug/kmemleak you can do: echo clear > /sys/kernel/debug/kmemleak test your kernel or modules echo scan > /sys/kernel/debug/kmemleak Then as usual to get your report with: cat /sys/kernel/debug/kmemleak Signed-off-by: Luis R.
