I freely confess that I have absolutely no idea what it doesn't like. It is complaining about this header comment, correct? /** * kmem_last_alloc_stack - Get return address and stack for last allocation * @object: object for which to find last-allocation return address. * @stackp: %NULL or pointer to location to place return-address stack. * @nstackp: maximum number of return addresses that may be stored. * * If the pointer references a slab-allocated object and if sufficient * debugging is enabled, return the return address for the corresponding * allocation. If stackp is non-%NULL in %CONFIG_STACKTRACE kernels running * the slub allocator, also copy the return-address stack into @stackp, * limited by @nstackp. Otherwise, return %NULL or an appropriate error * code using %ERR_PTR(). * * Return: return address from last allocation, %NULL or negative error code. */ Thanx, Paul
