Subject: Re: [resend v1 4/5] drivers/nvme/host/core.c: Convert to use disk_set_capacity
Date: Sat, 4 Jan 2020 22:27:39 +0000 [thread overview]
Message-ID: <BYAPR04MB57490FFCC025A88F4D97D40A86220@BYAPR04MB5749.namprd04.prod.outlook.com> (raw)
In-Reply-To: 20200102075315.22652-5-sblbir@amazon.com
Quick question here if user executes nvme ns-rescan /dev/nvme1
will following code result in triggering uevent(s) for
the namespace(s( for which there is no change in the size ?
If so is that an expected behavior ?
