[CRIU] Re: [PATCH 3/4] restorer: Do restore futex robust lists

[Pavel Emelyanov]

If the default value is not specified for an optional element, a type-specific
default value is used instead: for strings, the default value is the empty string.
For bools, the default value is false. For numeric types, the default value is
zero. For enums, the default value is the first value listed in the enum's type
definition.

Thanks,
Pavel
