SubjectRe: [resend v1 4/5] drivers/nvme/host/core.c: Convert to use disk_set_capacity
Date
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 ?
