From 8eff201b0021a5821cd71149a43805501f9373c1 Mon Sep 17 00:00:00 2001 From: David Marchand Date: Tue, 11 May 2021 13:33:58 +0200 Subject: [PATCH] net/ice: fix leak on thread termination A terminated pthread should be joined or detached so that its associated resources are released. The "ice-reset-" threads are used to service some reset task in the background, but they are never joined by the thread that created them. The easiest solution is to detach new threads. The Windows EAL did not provide a pthread_detach wrapper but there is no resource to release for Windows threads, so add an empty wrapper.
