## Summary Fix error handling and detach safety for threaded and work queue based IRQs: - Keep a threaded IRQ slot available when `kthread_create()` fails. - Avoid calling `kthread_delete(0)` when detaching an unused threaded IRQ. - Return `-ENOMEM` without attaching the IRQ when no work queue is available. - Release the work queue mutex when all queue slots are occupied and do not cache a failed queue creation. - Cancel pending IRQ work before clearing callback state and safely handle a concurrent detach in the worker callback. ## Impact bug fix only ## Testing Host: macOS 26.6.2 ARM64, Apple Clang 21.0.0. Target: sim:ostest . Build: cmake + ninja complete successfully with "Linking C executable nuttx". Runtime: ran ./nuttx and executed ostest; all enabled OSTest subtests completed without assertions or unexpected errors -- This is an automated message from the Apache Git Service.
