From 581434654e01ec79dd02c21448ac84e2ce2d1a64 Mon Sep 17 00:00:00 2001 From: Chen Ridong Date: Tue, 8 Oct 2024 11:24:58 +0000 Subject: workqueue: Adjust WQ_MAX_ACTIVE from 512 to 2048 WQ_MAX_ACTIVE is currently set to 512, which was established approximately 15 yeas ago. However, with the significant increase in machine sizes and capabilities, the previous limit of 256 concurrent tasks is no longer sufficient. Therefore, we propose to increase WQ_MAX_ACTIVE to 2048. and WQ_DFL_ACTIVE is 1024 now.
