From 69e8575dee424eebc4a3f96b5af11b858c5885e0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 28 Oct 2019 08:41:43 -0700 Subject: xfs: remove the dsunit and dswidth variables in There is no real need for the local variables here - either they are applied to the mount structure, or if the noalign mount option is set the mount will fail entirely if either is set. Removing them helps cleaning up the mount API conversion. Signed-off-by: Christoph Hellwig Reviewed-by: Eric Sandeen Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
