Subject: [patch 6/6] [PATCH] qeth: add wake_up on write channel
Date: Wed, 08 Feb 2012 11:19:50 +0100 [thread overview]
Message-ID: <20120208102029.681812945@de.ibm.com> (raw)
In-Reply-To: 20120208101944.272235343@de.ibm.com
[-- Attachment #1: 607-qeth-write-wake-up.diff --]
[-- Type: text/plain, Size: 901 bytes --]
From: Ursula Braun <ursula.braun@de.ibm.com>
To send commands on the write channel 8 buffers exist. If all
8 buffers are used, a wait is triggered on the write channel. When
such buffer are freed, a wake_up is needed. This patch adds the
missing wake_up in qeth_release_buffer().
This fix is especially important when running Communications
Controller for Linux on System z.
