Reorganize zpool(8) man page into sections Moved subcommand topics into individual manpages. Reordered and grouped the list of subcommands by topic. Moved concepts overview to `zpoolconcepts.8` and the long list of available pool properties to `zpoolprops.8`. Internal cross-references copied from `zpool.8` needed to be converted to `.Xr` external references to new subcommand manual pages. Move `autotrim` into lexical order, autotrim tacked onto the end of a list. Now it is in alphabetical order. Clarify attach/detach description. Description was too specific to command syntax. Overview clarifies reason for attaching or detaching a device. Clarify replace description, don't refer to subcommand arguments. Clarify split command description, say what split actually does and why you'd want to do it. Clarify description of upgrade, and simplify the zpool.8 wording of the zpool-upgrade(8) description. Clarify description of import, detail what zpool-import(8) actually does. Add appropriate SEE ALSO sections. Divided zpool subcommand manual pages need their own SEE ALSO sections. Also modified fsck.zfs.8 to point directly to zfs-scrub.8 and zed.8.in to include a direct reference to zfs-events.8 Reviewed-by: Matt Ahrens <matt@delphix.com> Reviewed-by: Kjeld Schouten <kjeld@schouten-lebbing.nl> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Ross Williams <ross@ross-williams.net> Closes #9564

Persistent L2ARC This commit makes the L2ARC persistent across reboots. We implement a light-weight persistent L2ARC metadata structure that allows L2ARC contents to be recovered after a reboot. This significantly eases the impact a reboot has on read performance on systems with large caches.
