+ * LibZFS_Core (lzc) is intended to replace most functionality in libzfs.
+ * It has the following characteristics:
+ *
+ * - Thread Safe. libzfs_core is accessible concurrently from multiple
+ * threads. This is accomplished primarily by avoiding global data
+ * (e.g. caching). Since it's thread-safe, there is no reason for a
+ * process to have multiple libzfs "instances". Therefore, we store
+ * our few pieces of data (e.g. the file descriptor) in global
+ * variables. The fd is reference-counted so that the libzfs_core
+ * library can be "initialized" multiple times (e.g. by different
+ * consumers within the same process).
+ *
+ * - Committed Interface. The libzfs_core interface will be committed,
+ * therefore consumers can compile against it and be confident that
+ * their code will continue to work on future releases of this code.
+ * Currently, the interface is Evolving (not Committed), but we intend
+ * to commit to it once it is more complete and we determine that it
+ * meets the needs of all consumers.
+ *
+ * - Programatic Error Handling. libzfs_core communicates errors with
+ * defined error numbers, and doesn't print anything to stdout/stderr.
+ *
+ * - Thin Layer. libzfs_core is a thin layer, marshaling arguments
+ * to/from the kernel ioctls. There is generally a 1:1 correspondence
+ * between libzfs_core functions and ioctls to /dev/zfs.
+ *
+ * - Clear Atomicity. Because libzfs_core functions are generally 1:1
+ * with kernel ioctls, and kernel ioctls are general atomic, each
+ * libzfs_core function is atomic. For example, creating multiple
+ * snapshots with a single call to lzc_snapshot() is atomic -- it
+ * can't fail with only some of the requested snapshots created, even
+ * in the event of power loss or system crash.
+ *
+ * - Continued libzfs Support. Some higher-level operations (e.g.
+ * support for "zfs send -R") are too complicated to fit the scope of
+ * libzfs_core. This functionality will continue to live in libzfs.
+ * Where appropriate, libzfs will use the underlying atomic operations
+ * of libzfs_core. For example, libzfs may implement "zfs send -R |
+ * zfs receive" by using individual "send one snapshot", rename,
+ * destroy, and "receive one snapshot" operations in libzfs_core.
+ * /sbin/zfs and /zbin/zpool will link with both libzfs and
+ * libzfs_core. Other consumers should aim to use only libzfs_core,
+ * since that will be the supported, stable interface going forwards.

+ * ZFS ioctls.
+ *
+ * This file handles the ioctls to /dev/zfs, used for configuring ZFS storage
+ * pools and filesystems, e.g. with /sbin/zfs and /sbin/zpool.
+ *
+ * There are two ways that we handle ioctls: the legacy way where almost
+ * all of the logic is in the ioctl callback, and the new way where most
+ * of the marshalling is handled in the common entry point, zfsdev_ioctl().
+ *
+ * Non-legacy ioctls should be registered by calling
+ * zfs_ioctl_register() from zfs_ioctl_init(). The ioctl is invoked
+ * from userland by lzc_ioctl().
+ *
+ * The registration arguments are as follows:
+ *
+ * const char *name
+ * The name of the ioctl. This is used for history logging. If the
+ * ioctl returns successfully (the callback returns 0), and allow_log
+ * is true, then a history log entry will be recorded with the input &
+ * output nvlists. The log entry can be printed with "zpool history -i".
+ *
+ * zfs_ioc_t ioc
+ * The ioctl request number, which userland will pass to ioctl(2).
+ * The ioctl numbers can change from release to release, because
+ * the caller (libzfs) must be matched to the kernel.
+ *
+ * zfs_secpolicy_func_t *secpolicy
+ * This function will be called before the zfs_ioc_func_t, to
+ * determine if this operation is permitted. It should return EPERM
+ * on failure, and 0 on success. Checks include determining if the
+ * dataset is visible in this zone, and if the user has either all
+ * zfs privileges in the zone (SYS_MOUNT), or has been granted permission
+ * to do this operation on this dataset with "zfs allow".
+ *
+ * zfs_ioc_namecheck_t namecheck
+ * This specifies what to expect in the zfs_cmd_t:zc_name -- a pool
+ * name, a dataset name, or nothing. If the name is not well-formed,
+ * the ioctl will fail and the callback will not be called.
+ * Therefore, the callback can assume that the name is well-formed
+ * (e.g. is null-terminated, doesn't have more than one '@' character,
+ * doesn't have invalid characters).
+ *
+ * zfs_ioc_poolcheck_t pool_check
+ * This specifies requirements on the pool state. If the pool does
+ * not meet them (is suspended or is readonly), the ioctl will fail
+ * and the callback will not be called. If any checks are specified
+ * (i.e. it is not POOL_CHECK_NONE), namecheck must not be NO_NAME.
+ * Multiple checks can be or-ed together (e.g. POOL_CHECK_SUSPENDED |
+ * POOL_CHECK_READONLY).
+ *
+ * boolean_t smush_outnvlist
+ * If smush_outnvlist is true, then the output is presumed to be a
+ * list of errors, and it will be "smushed" down to fit into the
+ * caller's buffer, by removing some entries and replacing them with a
+ * single "N_MORE_ERRORS" entry indicating how many were removed. See
+ * nvlist_smush() for details. If smush_outnvlist is false, and the
+ * outnvlist does not fit into the userland-provided buffer, then the
+ * ioctl will fail with ENOMEM.
+ *
+ * zfs_ioc_func_t *func
+ * The callback function that will perform the operation.
+ *
+ * The callback should return 0 on success, or an error number on
+ * failure. If the function fails, the userland ioctl will return -1,
+ * and errno will be set to the callback's return value. The callback
+ * will be called with the following arguments:
+ *
+ * const char *name
+ * The name of the pool or dataset to operate on, from
+ * zfs_cmd_t:zc_name. The 'namecheck' argument specifies the
+ * expected type (pool, dataset, or none).
+ *
+ * nvlist_t *innvl
+ * The input nvlist, deserialized from zfs_cmd_t:zc_nvlist_src. Or
+ * NULL if no input nvlist was provided. Changes to this nvlist are
+ * ignored. If the input nvlist could not be deserialized, the
+ * ioctl will fail and the callback will not be called.
+ *
+ * nvlist_t *outnvl
+ * The output nvlist, initially empty. The callback can fill it in,
+ * and it will be returned to userland by serializing it into
+ * zfs_cmd_t:zc_nvlist_dst. If it is non-empty, and serialization
+ * fails (e.g. because the caller didn't supply a large enough
+ * buffer), then the overall ioctl will fail. See the
+ * 'smush_nvlist' argument above for additional behaviors.
+ *
+ * There are two typical uses of the output nvlist:
+ * - To return state, e.g. property values. In this case,
+ * smush_outnvlist should be false. If the buffer was not large
+ * enough, the caller will reallocate a larger buffer and try
+ * the ioctl again.
+ *
+ * - To return multiple errors from an ioctl which makes on-disk
+ * changes. In this case, smush_outnvlist should be true.
+ * Ioctls which make on-disk modifications should generally not
