From fd8e597ba4afb769a8fb642555a6e0c5349a6ae8 Mon Sep 17 00:00:00 2001 From: Konstantin Khlebnikov Date: Fri, 19 May 2017 10:18:49 +0300 Subject: [PATCH] e1000e: use disable_hardirq() also for MSIX vectors in e1000_netpoll() Replace disable_irq() which waits for threaded irq handlers with disable_hardirq() which waits only for hardirq part.
