From: Thomas Gleixner Date: Thu, 1 Apr 2010 20:20:57 +0200 Subject: drivers: net: gianfar: Make RT aware Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/3.12/patches-3.12.0-rt2.tar.xz The adjust_link() disables interrupts before taking the queue locks. On RT those locks are converted to "sleeping" locks and therefor the local_irq_save/restore must be converted to local_irq_save/restore_nort.
