Inter-platform coordination

Ideas for projects that would help coordinate changes between platforms:

  • Mechanism for pull changes from one place to another
    • Make it easier to build, test, code review, and integrate ZFS changes into illumos
  • Cross-Platform Test Suite
    • One sourcebase rather than porting STF to every platform?
  • Userland ZFS
    • we already have ztest / libzpool
    • want to expand this to also be able to test more of zfs in userland
    • want to be able to run /sbin/zfs, /sbin/zpool against userland implementation
    • want to be able to run most of testrunner (and/or STF) test suite against userland implementation
  • ZFS Version Feature Flags
    • Import ZFSOnLinux sa=xattr into Illumos

General features

  • device removal
  • resumable send/receive
    • work in progress at Delphix
  • Storage of small files in dnode
    • work in progress at Delphix
  • Reflink[1] support
  • Unified ashift handling [2]
  • Collapsible ZAP objects (e.g. fatzip -> microzap downgrades)
  • Raidz Hybrid Allocator (preferably compatible with pool version 29 for Solaris 10u11 compatibility)
  • Replace ZIO caches with explicit pages.
    • Subproject: Document useful kernel interfaces for page manipulation on various platforms
  • Improved SPA namespace collision management
    • Mostly needed by virtual machine hosts
    • work in progress in Gentoo
    • Temporary pool names in zpool import [3]
    • Temporary pool names in zpool create
