OpenZFS 8558, 8602 - lwp_create() returns EAGAIN
8558 lwp_create() returns EAGAIN on system with more than 80K ZFS filesystems
On a system with more than 80K ZFS filesystems, we've seen cases
where lwp_create() will start to fail by returning EAGAIN. The
problem being, for each of those 80K ZFS filesystems, a taskq will
be created for each dataset as part of the ZIL for each dataset.
Porting Notes:
- The new nomem taskq kstat was dropped.
- Added module options and documentation for new tunings
zfs_zil_clean_taskq_nthr_pct, zfs_zil_clean_taskq_minalloc,
zfs_zil_clean_taskq_maxalloc, and zfs_sync_taskq_batch_pct.
