Subject: support multiple block devices per file system for block-style layouts
Date: Mon, 23 Mar 2026 08:07:16 +0100	[thread overview]
Message-ID: <20260323070746.2940140-1-hch@lst.de> (raw)

Hi all,

this series adds support for exporting multiple block devices using
block-style from nfsd, and uses that to implement support for the XFS
RT device.  To get there is also first cleans up the block-style layout
interface in exportfs.
