Previously only `ident` and generic types were supported in the `{try_}{pin_}init!` macros. This patch allows arbitrary path fragments, so for example `Foo::Bar` but also very complex paths such as `<Foo as Baz>::Bar::<0, i32>`. Internally this is accomplished by using `path` fragments. Due to some peculiar declarative macro limitations, we have to "forget" certain additional parsing information in the token trees. This is achieved by using the `paste!` proc macro. It does not actually modify the input, since no `[< >]` will be present in the input, so it just strips the information held by declarative macros. For example, if a declarative macro takes `$t:path` as its input, it cannot sensibly propagate this to a macro that takes `$($p:tt)*` as its input, since the `$t` token will only be considered one `tt` token for the second macro. If we first pipe the tokens through `paste!`, then it parses as expected.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
