Nevertheless, the performances are unacceptable. The original McKusick algorithm implements a quick fit allocation scheme, based on bucket management of ^2-sized chunks, which automatically switches to a page-based allocation method for blocks larger than twice the base page size. This variant maintains the free page list in AVL trees for fast lookups of multi-page memory ranges, and pages holding bucketed memory have a quick allocation bitmap to manage their blocks internally. The current implementation can replace TLSF for delivering process-local memory with similar performances but lesser overhead with small sizes. Most importantly, a kernel variant of HEAPMEM should replace the Cobalt core allocator. Likewise, heapobj-pshared which is beyond repair should be replaced with a process-shareable variant as well, assuming the average size and allocation patterns of real-time objects are similar in all contexts.

copperplate/registry: switch back to private memory for fs objects
Partially revert #8e606e681, keeping registry_add_dir/file() routines
free from Cobalt mode switches, a property which some applications
might assume when creating specific rt objects (e.g. Alchemy's
mutexes, condvars).

net: create sysfs nodes for net devices
Each rtnet device registered with the stack is represented by a node
into /sys/devices/virtual/rtnet/.
Setting the address of the real device probed by the kernel into the
rtnet_device.sysbind field before calling rt_register_rtnetdev(),
causes the "adapter" symlink to be installed in the newly created
attribute directory, pointing at that device.
e.g.
static int probe_handler(struct pci_dev *pdev, const struct pci_device_id
*ent)
{
...
rtdev->sysbind = &pdev->dev;
...
ret = rt_register_rtnetdev(rtdev);
...
}
