Richard Yao d4bf6d8429 Disable direct reclaim in taskq worker threads on Linux 3.9+ ... Illumos does not have direct reclaim and code run inside taskq worker threads is not designed to deal with it. Allowing direct reclaim inside a worker thread can therefore deadlock. We set PF_MEMALLOC_NOIO through memalloc_noio_save() to indicate to the kernel's reclaim code that we are inside a context where memory allocations cannot be allowed to block on filesystem activity.
