From 3b3dce05279b97525741b7949208017307e05621 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 21 Jun 2016 09:52:47 +1000 Subject: [PATCH] xfs: make xfs_bmbt_to_iomap available outside of xfs_pnfs.c And ensure it works for RT subvolume files an set the block device, both of which will be needed to be able to use the function in the buffered write path.
