static int zfs_check_clearable	(	char *	dataset,

Removes properties from the given props list that fail permission checks needed to clear them and to restore them in case of a receive error.

For each property, make sure we have both set and inherit permissions.

Returns the first error encountered if any permission checks fail. If the caller provides a non-NULL errlist, it also gives the complete list of names of all the properties that failed a permission check along with the corresponding error numbers. The caller is responsible for freeing the returned errlist.

If every property checks out successfully, zero is returned and the list pointed at by errlist is NULL.

Determine the settings for utf8only, normalization and casesensitivity.

Specific values may have been requested by the creator and/or we can inherit values from the parent dataset. If the file system is of too early a vintage, a creator can not request settings for these properties, even if the requested setting is the default value. We don't actually want to create dsl properties for these, so remove them from the source nvlist after processing.

Parameters:

[in]	os	parent objset pointer (NULL if root fs)
[in]	os	zpl version to use if unspecified in createprops
[in]	os	fuids allowed in this version of the spa?
[in]	os	list of properties requested by creator
[out]	zplprops	values for the zplprops we attach to the master node object
[out]	is_ci	true if requested file system will be purely case-insensitive

int zfs_set_prop_nvlist	(	const char *	dsname,

		nvlist_t **	errlist
	)

This function is best effort.

If it fails to set any of the given properties, it continues to set as many as it can and returns the first error encountered. If the caller provides a non-NULL errlist, it also gives the complete list of names of all the properties it failed to set along with the corresponding error numbers. The caller is responsible for freeing the returned errlist.

If every property is set successfully, zero is returned and the list pointed at by errlist is NULL.

Find a zfsvfs_t for a mounted filesystem, or create our own, in which case its z_vfs will be NULL, and it will be opened as the owner.

If 'writer' is set, the z_teardown_lock will be held for RW_WRITER, which prevents all vnode ops from running.
