From: Andrii Nakryiko <andriin@xxxxxx> [ Upstream commit aef70a1f44c0b570e6345c02c2d240471859f0a4 ] Some compilers emit warning for potential uninitialized next_id usage. The code is correct, but control flow is too complicated for some compilers to figure this out. Re-initialize next_id to satisfy compiler.
