Re: Question about memory leak detector giving false positive report for net/core/flow.c

I tried this but it's tricky. The problem is that the percpu pointer
returned by alloc_percpu() does not directly point to the per-cpu chunks
and kmemleak would report most percpu allocations as leaks. So far the
workaround is to simply mark the alloc_percpu() objects as never leaking
and at least we avoid false positives in other areas. See the patch
below (note that you have to increase the CONFIG_KMEMLEAK_EARLY_LOG_SIZE
as there are many alloc_percpu() calls before kmemleak is fully
initialised):

Seems that kernel.org is out and so tejon wont be seeing these.
