no1wudi opened a new pull request, #3025:
URL: https://github.com/apache/nuttx-apps/pull/3025
## Summary
This change enhances NuttX's test coverage by validating mutex behavior
in non-standard relocation scenarios, while explicitly noting this
extends beyond POSIX specifications. The test helps prevent regressions
in edge-case mutex handling.
* Add test case for mutex move functionality in ostest
* Verifies correct behavior when a mutex is relocated in memory
* Introduces new test structure with thread argument passing
* Includes validation of mutex state across thread operations
* Related to Rust language discussion:
https://github.com/rust-lang/rust/pull/138400
## Impact
* New feature added?: YES - Adds new mutex move test scenario
* Impact on user?: NO - Test suite enhancement only
* Impact on build?: NO - Existing test infrastructure used
* Impact on hardware?: NO - Pure software validation
* Impact on documentation?: NO - No user-facing docs changed
* Impact on security?: NO - Test-only code
* Impact on compatibility?: NO - Maintains existing POSIX compliance
