Subject: Rollup merge of #41061 - arielb1:parent-lock, r=eddyb
X-Git-Url: https://git.lizzy.rs/?a=commitdiff_plain;h=996f06fe3597eeb2c671a34cf16d2b29aec961e7;p=rust.git

Rollup merge of #41061 - arielb1:parent-lock, r=eddyb

cstore: return an immutable borrow from `visible_parent_map`

This prevents an ICE when `visible_parent_map` is called multiple times, for example when an item referenced in an impl signature is imported from an  `extern crate` statement occurs within an impl.

Fixes #41053.
