Executive overview: this is the easiest improvement to understand in the current set of proposed features; exactly what it says on the tin: L2ARC that persists across reboots, and TRIM support for the underlying devices in a pool. TRIM function supports both Trim and Unmap, as appropriate to underlying storage. | Executive overview: this is the easiest improvement to understand in the current set of proposed features; exactly what it says on the tin: L2ARC that persists across reboots, and TRIM support for the underlying devices in a pool.

pL2ARC status: Code [[https://www.illumos.org/issues/3525 out for review on illumos]] for several years, waiting on TRIM to land. Suspect ZFS on Linux will merge it once they merge TRIM. | |||
TRIM status: Likewise, code [[https://www.illumos.org/issues/6363 out for review on illumos]] and [[https://github.com/openzfs/openzfs/pull/172 OpenZFS]] for a while, but not yet merged. ZFS on Linux was waiting on OpenZFS to merge it first, but now [[https://github.com/zfsonlinux/zfs/pull/7363 looks like it's just going to merge it shortly]]. | |||
'''How to help''': pushing the code the last few inches across the finish lines by refreshing the patches against latest master branches and fixing any issues reviewers identify. | |||
