Some of our links use relative paths in order to point to files in the
source tree, e.g.:
//! C header: [`include/linux/printk.h`](../../../../include/linux/printk.h)
/// [`struct mutex`]: ../../../../include/linux/mutex.h
These are problematic because they are hard to maintain and do not support
`O=` builds.
Instead, provide support for `srctree`-relative links, e.g.:
//! C header: [`include/linux/printk.h`](srctree/include/linux/printk.h)
/// [`struct mutex`]: srctree/include/linux/mutex.h
The links are fixed after `rustdoc` generation to be based on the absolute
path to the source tree.
Essentially, this is the automatic version of Tomonori's fix [1],
suggested by Gary [2].

Currently, `CondVar::wait()` is an interruptible wait, and this is
different than `wait_event()` in include/linux/wait.h (which is an
uninterruptible wait). To avoid confusion between different APIs on the
interruptible/uninterruptible, make `CondVar::wait()` an uninterruptible
wait same as `wait_event()`, also rename the old `wait()` to
`CondVar::wait_interruptible()`.

Clippy triggered a false positive on its `new_ret_no_self` lint
when using the `pin_init!` macro. Since Rust 1.67.0, that does
not happen anymore, since Clippy learnt to not warn about
`-> impl Trait<Self>` [1][2].
The kernel nowadays uses Rust 1.72.1, thus remove the `#[allow]`.

This is the traditional condition variable or monitor synchronisation
primitive. It is implemented with C's `wait_queue_head_t`.
It allows users to release a lock and go to sleep while guaranteeing
that notifications won't be missed. This is achieved by enqueuing a wait
entry before releasing the lock.
