[pbs-devel] [PATCH proxmox 5/9] procfs: add variable bindings for std::fs::read

[Maximiliano Sandoval <m.sandoval@proxmox.com>]

These will produce an error in edition 2024 otherwise. The reason this
is needed is because the `unsafe` block has its own scope.

The bytes were defined inside of the let-mut block to preserve the
lifetime they had before this commit.
