Subject: [PULL for-6.0 v2 03/10] hw/block/nvme: fix the nsid 'invalid' value
Date: Wed,  7 Apr 2021 07:46:28 +0200	[thread overview]
Message-ID: <20210407054635.189440-4-its@irrelevant.dk> (raw)
In-Reply-To: <20210407054635.189440-1-its@irrelevant.dk>

From: Klaus Jensen <k.jensen@samsung.com>

The `nvme_nsid()` function returns '-1' (FFFFFFFFh) when the given
namespace is NULL. Since FFFFFFFFh is actually a valid namespace
identifier (the "broadcast" value), change this to be '0' since that
actually *is* the invalid value.
