Alan Somers b64afa41d5 Better control the thread pool size when mounting datasets ... Ever since a10d50f999, ZFS has mounted file systems in parallel when importing a pool. It uses a fixed size of 512 for the thread pool. But since c183d164aa, it has also imported pools in parallel. So the total number of threads at one time is 513 * npools + 1. That can easily exceed the system's limit on the number of threads per process, which will cause one or more pools to be unable to allocate any worker threads, forcing them to fallback to slow serial mounting . To forestall that, manage the threadpool size in /sbin/zpool, not libzfs. Use the same size (512), but divided by the number of pools. This is a backwards-incompatible change to the libzfs abi.
