From 3398a4005f0c8ced67a9071475562d435d88b7a6 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 14 Jun 2017 21:30:44 -0700 Subject: [PATCH] xfs: remove XFS_HSIZE XFS_HSIZE is an extremly confusing way to calculate the size of handle_t. Given that handle_t always only had two sizes, and one of them isn't even covered by XFS_HSIZE to start with just remove the macro and use a constant sizeof expression. Note that XFS_HSIZE isn't used in xfsprogs, xfsdump or xfstests either. Signed-off-by: Christoph Hellwig Reviewed-by: Eric Sandeen Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J.
