Subject: drivers: net: gianfar: Make RT aware
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/3.10/patches-3.10.4-rt1.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.
