10841 predictive prefetch disabled on new pools until export/reboot
illumos/illumos-gate@0ce4bbcb47d8f86307fb8d2c84fd0f4e070f576e https://github.com/illumos/illumos-gate/commit/0ce4bbcb47d8f86307fb8d2c84fd0f4e070f576e https://www.illumos.org/issues/10841 ZoL 944a37248a0 predictive prefetch disabled on new pools until export/reboot When a pool is initially created (by `zpool create`), predictive prefetch is inadvertently disabled, until the pool is export/import-ed, or the machine is rebooted. When device removal was introduced, we added some code to disable predictive prefetching until indirect vdevs have been loaded. This resulted in the "default state" of prefetch being disabled, until we proactively enable it after indirect vdevs are loaded. Unfortunately this resulted in a few bugs where in some code paths we neglect to enable predictive prefetch. The first of these was fixed by https://github.com/zfsonlinux/zfs/commit/20507534d4ede14d4dd82c99fc8d461704ce7419 This commit fixes another case where we also need to explicitly enable predictive prefetch, when the pool is initially created.
