From fb7855a6b58b045f60a7456096da29842e9ca079 Mon Sep 17 00:00:00 2001 From: Kaushlendra Kumar Date: Wed, 10 Sep 2025 20:44:19 +0530 Subject: [PATCH] refperf: Remove redundant kfree() after torture_stop_kthread() Remove unnecessary kfree(main_task) call in ref_scale_cleanup() as torture_stop_kthread() already handles the memory cleanup for the task structure internally. The additional kfree(main_task) call after torture_stop_kthread() is redundant and confusing since torture_stop_kthread() sets the pointer to NULL, making this a no-op. This pattern is consistent with other torture test modules where torture_stop_kthread() is called without explicit kfree() of the task pointer, as the torture framework manages the task lifecycle internally.
