From 30fa529e3b2e6f1da277ef8525e4ce7979c57c57 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 24 Oct 2019 22:25:38 -0700 Subject: xfs: add a xfs_inode_buftarg helper Add a new xfs_inode_buftarg helper that gets the data I/O buftarg for a given inode. Replace the existing xfs_find_bdev_for_inode and xfs_find_daxdev_for_inode helpers with this new general one and cleanup some of the callers. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J.
