Same reason as rust-lang/log#536 : `cfg_if` is only used in a single place and `tracing` is used by many other crates, so even removing one dependency will be beneficial. Signed-off-by: Jiahao XU <Jiahao_XU@outlook.com>

Remove dependency `cfg-if` and replace `cfg_if::cfg_if!` with a `const fn get_max_level_inner() -> LevelFilter` and uses `if cfg!(...)` inside. Using if in const function is stablised in [1.46](https://github.com/rust-lang/rust/blob/master/RELEASES.md#version-1460-2020-08-27) so this should work fine in msrv 1.56 Signed-off-by: Jiahao XU <Jiahao_XU@outlook.com> ; Conflicts: ; tracing/Cargo.toml ; tracing/src/level_filters.rs

# 0.1.38 (April 25th, 2023) This `tracing` release changes the `Drop` implementation for `Instrumented` `Future`s so that the attached `Span` is entered when dropping the `Future`. This means that events emitted by the `Future`'s `Drop` implementation will now be recorded within its `Span`. It also adds `#[inline]` hints to methods called in the `event!` macro's expansion, for an improvement in both binary size and performance. Additionally, this release updates the `tracing-attributes` dependency to [v0.1.24][attrs-0.1.24], which updates the [`syn`] dependency to v2.x.x. `tracing-attributes` v0.1.24 also includes improvements to the `#[instrument]` macro; see [the `tracing-attributes` 0.1.24 release notes][attrs-0.1.24] for details. ### Added - `Instrumented` futures will now enter the attached `Span` in their `Drop` implementation, allowing events emitted when dropping the future to occur within the span (#2562) - `#[inline]` attributes for methods called by the `event!` macros, making generated code smaller (#2555) - **attributes**: `level` argument to `#[instrument(err)]` and `#[instrument(ret)]` to override the level of the generated return value event (#2335) - **attributes**: Improved compiler error message when `#[instrument]` is added to a `const fn` (#2418) ### Changed - `tracing-attributes`: updated to [0.1.24][attrs-0.1.24] - Removed unneeded `cfg-if` dependency (#2553) - **attributes**: Updated [`syn`] dependency to 2.0 (#2516) ### Fixed - **attributes**: Fix `clippy::unreachable` warnings in `#[instrument]`-generated code (#2356) - **attributes**: Removed unused "visit" feature flag from `syn` dependency (#2530) ### Documented - **attributes**: Documented default level for `#[instrument(err)]` (#2433) - **attributes**: Improved documentation for levels in `#[instrument]` (#2350) Thanks to @nitnelave, @jsgf, @Abhicodes-crypto, @LukeMathWalker, @andrewpollack, @quad, @klensy, @davidpdrsn, @dbidwell94, @ldm0, @NobodyXu, @ilsv, and @daxpedda for contributing to this release!

Motivation
Same reason as rust-lang/log#536 :
cfg_ifis only used in a single place andtracingis used by many other crates, so even removing one dependency will be beneficial.Solution
Remove dependency
cfg-ifand replacecfg_if::cfg_if!with aconst fn get_max_level_inner() -> LevelFilterand usesif cfg!(...)inside.Using if in const function is stablised in 1.46 so this should work fine in msrv 1.56
