move [`mixed_attributes_style`] to late pass and stop it from linting on different kind of attributes
Do not warn on .map(_::clone) for Arc, Rc, and their weak variants
Those constructions are idiomatic, and using `Arc::clone(x)` and `Rc::clone(x)` is often the recommended way of cloning a `Arc` or a `Rc`.
Fix#12528
changelog: [`map_clone`]: do not warn on `.map(_::clone)` for `Arc`, `Rc`, and their `Weak` variants
Fix infinite loop in `cast_sign_loss` when peeling unwrap method calls
Fixes#12506
The lint wants to peel method calls but didn't actually reassign the expression, leading to an infinite loop.

Mention `size_hint()` effect in `flat_map_option` lint documentation.
The previous documentation for `flat_map_option` mentioned only readability benefits, but there is also at least one performance benefit: the `size_hint()` upper bound is preserved, whereas `flat_map().size_hint()` is always `(0, None)`.
Program demonstrating this difference:
```rust
fn main() {
let evens = |i| if i % 2 == 0 { Some(i) } else { None };
dbg!(
[1, 2, 3].iter().flat_map(evens).size_hint(),
[1, 2, 3].iter().filter_map(evens).size_hint(),
);
}
```
changelog: [`flat_map_option`]: Mention the benefit to `size_hint()`.
Fix documentation typo "appects" > "affects"
changelog: none
This fixes a typo in the `iter_filter_is_some` and `iter_filter_is_ok` lint documentation.
Add xFrednet back to the reviewing rotation 🎉
You know what? Having a work-life balance is boring.
I truly enjoyed having a free few weeks, and learned that I need to take a break every once in a while, but not doing reviews feels weird. So, this is me coming back for more :D

Disable `cast_lossless` when casting to u128 from any (u)int type
Fixes https://github.com/rust-lang/rust-clippy/issues/12492
Disables `cast_lossless` when casting to u128 from any int or uint type. The lint states that when casting to any int type, there can potentially be lossy behaviour if the source type ever exceeds the size of the destination type in the future, which is impossible with a destination of u128.
It's possible this is a bit of a niche edge case which is better addressed by just disabling the lint in code, but I personally couldn't think of any good reason to still lint in this specific case - maybe except if the source is a bool, for readability reasons :).
changelog: FP: `cast_lossless`: disable lint when casting to u128 from any (u)int type
Make `assigning_clones` MSRV check more precise
Continuation of #12511
`clone_into` is the only suggestion subject to the 1.63 MSRV requirement, and the lint should still emit other suggestions regardless of the MSRV.
changelog: [assigning_clones]: only apply MSRV check to `clone_into` suggestions.
`assigning_clones` should respect MSRV
Fixes: #12502
This PR fixes the `assigning_clones` lint suggesting to use `clone_from` or `clone_into` on incompatible MSRVs.
`assigning_clones` will suggest using either `clone_from` or `clone_into`, both of which were stabilized in 1.63. If the current MSRV is below 1.63, the lint should not trigger.
changelog: [`assigning_clones`]: don't lint when the MSRV is below 1.63.
Use hir::Node helper methods instead of repeating the same impl multiple times
I wanted to do something entirely different and stumbled upon a bunch of cleanups
[`map_entry`]: call the visitor on the local's `else` block
Fixes#12489
The lint already has all the logic it needs for figuring out if it can or can't suggest a closure if it sees control flow expressions like `break` or `continue`, but it was ignoring the local's else block, which meant that it didn't see the `return None;` in a `let..else`.
changelog: [`map_entry`]: suggest `if let` instead of a closure when `return` expressions exist in the else block of a `let..else`
new restriction lint: `integer_division_remainder_used`
Fixes https://github.com/rust-lang/rust-clippy/issues/12391
Introduces a restriction lint which disallows the use of `/` and `%` operators on any `Int` or `Uint` types (i.e., any that use the default `Div` or `Rem` trait implementations). Custom implementations of these traits are ignored.
----
changelog: Add new restriction lint [`integer_division_remainder_used`]
[`option_option`]: Fix duplicate diagnostics
Relates to #12379
This `option_option` lint change skips checks against `ty`s inside `field_def`s defined by external macro to prevent duplicate diagnostics to the same span `ty` by multiple `Struct` definitions.

changelog: [`option_option`]: Fix duplicate diagnostics
move `readonly_write_lock` to perf
[There haven't been any issues](https://github.com/rust-lang/rust-clippy/issues?q=is%3Aissue+readonly_write_lock) since its creation and it's a pretty useful lint I think, so I'd say it's worth giving it a try?
Did a lintcheck run on 300 crates with no results, but I guess `RwLock` is usually not something that's used much in libraries.
changelog: move [`readonly_write_lock`] to perf (now warn-by-default)
fix [`dbg_macro`] FN when dbg is inside some complex macros
fixes: #12131
It appears that [`root_macro_call_first_node`] only detects `println!` in the following example:
```rust
println!("{:?}", dbg!(s));
```
