Konstantin Belousov 165a3b418f When a UFS node is truncated to the zero length, e.g. by explicit ... truncate(2) call, or by being removed or truncated on open, either new softupdate freeblks structure is allocated to track the freed blocks of the node, or truncation is done syncronously when too many SU dependencies are accumulated. The decision does not take into account the allocated freeblks dependencies, allowing workloads that do huge amount of truncations to exhaust the kernel memory. Take the number of allocated freeblks into consideration for softdep_slowdown().
