Linux 5.17 commit torvalds/linux@5dfbfe71e enables "the idmapping infrastructure to support idmapped mounts of filesystems mounted with an idmapping". Update the OpenZFS accordingly to improve the idmapped mount support. This pull request contains the following changes: - xattr setter functions are fixed to take mnt_ns argument. Without this, cp -p would fail for an idmapped mount in a user namespace. - idmap_util is enhanced/fixed for its use in a user ns context. - One test case added to test idmapped mount in a user ns.
