David points out that the idr_remove_all() function returns unused slabs
to the kmem cache, but needs to zero them first or else they will be
uninitialized upon next use. This causes crashes which have been observed
in the firewire subsystem.
He fixed this by zeroing the object before freeing it in idr_remove_all().
But we agree that simply removing the constructor and zeroing the object
at allocation time is simpler than relying upon slab constructor machinery
and might even be faster.
This problem was introduced by "idr: make idr_remove rcu-safe" (commit
