[ubuntu/xenial-proposed] zfs-linux 0.6.5.6-0ubuntu20 (Accepted)

[Colin Ian King]

zfs-linux (0.6.5.6-0ubuntu20) xenial; urgency=medium

  * Fix mmap'd libaio read on non-prefaulted page deadlock (LP: #1754584)
    - Revert previous fix as there still is a potential for deadlock
      on the prefaulted page(s). Resolve the issue by only taking a
      reference on the page when copying it and not the page lock.
      The inode range lock protects against concurrent updates via
      zfs_read() and zfs_write().
