[**\[Experimental Bot, please feedback here\]**](https://github.com/search?q=repo%3Aapache%2Fnuttx+13552&type=issues) The PR summary does not fully meet NuttX requirements. Here's a breakdown and suggestions for improvement: **Strengths:** * **Clear problem description:** The summary clearly explains the bug caused by the original change (used after free issue during reboot). * **Rationale for revert:** The justification for reverting is well-explained (minimal performance gain vs. introduced bug). * **Impact is concise:** Clearly states the PR is a bug fix. * **Testing mentioned:** Mentions local testing, which is a good start. **Areas for Improvement:** * **Missing Technical Details:** * **Functional Change:** The summary mentions reverting file pre-allocation but lacks specifics on what code is being reverted and how the file handling mechanism will work after the revert. * **How Revert Works:** A brief explanation of how reverting solves the "used after free" issue would be beneficial (e.g., "Reverting ensures that file handles are released correctly during the shutdown process..."). * **Incomplete Testing Information:** * **No Build Host Details:** Specify the operating system, CPU architecture, and compiler used for local testing. * **No Target Details:** Provide information about the target architecture and board configuration used for testing. * **Missing Logs:** The "Testing logs before change" and "Testing logs after change" sections are empty. Include relevant log snippets demonstrating the bug before the revert and the fix afterward. **Revised Summary (Example):** This PR reverts commit 086834aae1722af2797fd5d4d0f79226ac11c2e9, which introduced pre-allocated task files to improve performance. However, this change caused a "used after free" issue during reboot due to the way pre-allocated files and their associated groups are released. This revert removes the pre-allocation mechanism, reverting to the original file handling logic. This ensures that file handles are released correctly during shutdown, preventing the "used after free" error. **Revised Testing (Example):** **Build Host(s):** Linux (Ubuntu 20.04), x86_64, GCC 9.4.0 **Target(s):** SIM, qemu-system-arm **Testing logs before change:** ``` [Relevant log output showing the "used after free" error during reboot] ``` **Testing logs after change:** ``` [Relevant log output showing the reboot process completing successfully without errors] ``` -- This is an automated message from the Apache Git Service.
