Tell kmemcheck to allocate the shadow memory which stores the status of\n each byte in the allocation proper, e.g. whether it is initialized or\n uninitialized.\n2. Tell kmemcheck which parts of memory that should be marked uninitialized.\n There are actually a few more states, such as \"not yet allocated\" and\n \"recently freed\".\n\nIf a slab cache is set up using the SLAB_NOTRACK flag, it will never return\nmemory that can take page faults because of kmemcheck.\n\nIf a slab cache is NOT set up using the SLAB_NOTRACK flag, callers can still\nrequest memory with the __GFP_NOTRACK flag. This does not prevent the page\nfaults from occuring, however, but marks the object in question as being\ninitialized so that no warnings will ever be produced for this object.\n\nIn addition to (and in contrast to) __GFP_NOTRACK, the\n__GFP_NOTRACK_FALSE_POSITIVE flag indicates that the allocation should\nnot be tracked _because_ it would produce a false positive.
