Open pools asynchronously after module load One of the side effects of calling zvol_create_minors() in zvol_init() is that all pools listed in the cache file will be opened. Depending on the state and contents of your pool this operation can take a considerable length of time. Doing this at load time is undesirable because the kernel is holding a global module lock. This prevents other modules from loading and can serialize an otherwise parallel boot process. Doing this after module inititialization also reduces the chances of accidentally introducing a race during module init. To ensure that /dev/zvol/<pool>/<dataset> devices are still automatically created after the module load completes a udev rules has been added. When udev notices that the /dev/zfs device has been create the 'zpool list' command will be run. This then will cause all the pools listed in the zpool.cache file to be opened. Because this process in now driven asynchronously by udev there is the risk of problems in downstream distributions.

Add dracut support To simplify the process of using zfs as your root filesystem a zfs-drucat sub-package has been added. This sub-package adds a zfs dracut module which allows your initramfs to be rebuilt with zfs support. The process for doing this is still complicated but there is clearly interest from the community about getting this working well and documented. This should help lay some of the groundwork. Longer term these changes should be pushed in the upstream dracut package. Once that occurs this subpackage will no longer be required for new systems, however we may want to conditionally build this package in the future for systems running older dracut versions.

Update for Dracut-010 Update Dracut module for Dracut-010 and fix race conditions that caused boot to fail on MP systems. Add support for zfs_force flag and parsing of spl_hostid from kernel command line.

Add `zfs allow` and `zfs unallow` support ZFS allows for specific permissions to be delegated to normal users with the `zfs allow` and `zfs unallow` commands. In addition, non- privileged users should be able to run all of the following commands: * zpool [list \| iostat \| status \| get] * zfs [list \| get] Historically this functionality was not available on Linux. In order to add it the secpolicy_* functions needed to be implemented and mapped to the equivalent Linux capability. Only then could the permissions on the `/dev/zfs` be relaxed and the internal ZFS permission checks used. Even with this change some limitations remain. Under Linux only the root user is allowed to modify the namespace (unless it's a private namespace). This means the mount, mountpoint, canmount, unmount, and remount delegations cannot be supported with the existing code. It may be possible to add this functionality in the future. This functionality was validated with the cli_user and delegation test cases from the ZFS Test Suite. These tests exhaustively verify each of the supported permissions which can be delegated and ensures only an authorized user can perform it. Two minor bug fixes were required for test-running.py. First, the Timer() object cannot be safely created in a `try:` block when there is an unconditional `finally` block which references it. Second, when running as a normal user also check for scripts using the both the .ksh and .sh suffixes. Finally, existing users who are simulating delegations by setting group permissions on the /dev/zfs device should revert that customization when updating to a version with this change.
