From 63ea3cf07639ec8ef5bd2c3f457eb54b6cd33198 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Sun, 15 Jun 2025 13:11:58 -0400 Subject: workqueue: Basic memory allocation profiling support Hook alloc_workqueue and alloc_workqueue_attrs() so that they're accounted to the callsite. Since we're doing allocations on behalf of another subsystem, this helps when using memory allocation profiling to check for leaks.
