Sloppy coding in this function could lead to leaking a VM buffer pin, or to attempting to free the same pin twice. Repair.

Documentation says it clearly. 4 (bit 2), is only to disable the dmesg / kernel log messages when the drop_caches is issued.

Those blocks of memory are called „pages“ and for efficiency in Linux kernel the size of allocated memory is 4kB. This same routine processes the "mem=" option if present and makes appropriate adjustments to VM parameters. We return to commandline in parse_options() (called by start_kernel() ) which processes some "in-kernel" parameters (currently "init=" and environment/arguments for init) and passes each word to checksetup() . uint32_t free_mem = alloc - len; // check if buffer needs to be reallocated: if (free_mem < req + seplen + 1) {uint64_t to_alloc = alloc + (req + seplen) * 2 + 4096; _buffer = mem_realloc (vm, _buffer, (uint32_t)to_alloc); if (!_buffer) {mem_free (_buffer); RETURN_ERROR_SIMPLE ();} alloc = (uint32_t)to_alloc;} // copy s2 to into buffer: memcpy (_buffer+len, s2, req); I suspect this is why setting 'memory_pools off' on the non-NOVM squids on FreeBSD is reported to work better - the VM/buffer system could be competing with squid to cache the same pages.
