FYI
If you integrate linux_idr.c from FreeBSD-11-current, this problem and a
few others should already be solved:
For example there:
while ((il = idr_find_layer_locked(idr, i)) != NULL) {
The following loop is buggy:
for (;i < (i & ~IDR_MASK) + IDR_SIZE; i++) {
if (il->ary[i & IDR_MASK]) {
*nextidp = i;
And equivalent to a "while (true)", which I believe this is not the
intention.
