Subject: [Qemu-devel] [PATCH for-2.4 06/10] block/iscsi: increase retry count
Date: Thu, 16 Apr 2015 14:18:46 +0200 [thread overview]
Message-ID: <1429186730-3866-7-git-send-email-pl@kamp.de> (raw)
In-Reply-To: <1429186730-3866-1-git-send-email-pl@kamp.de>
The idea is that a command is retried in a BUSY condition
up a time of approx. 60 seconds before it is failed. This should
be far higher than any command timeout in the guest.
