From 5a3930e27ef95893f039b9ec127a48139fcc8ca5 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 26 Feb 2020 17:30:41 -0800 Subject: xfs: improve xfs_forget_acl Move the function to xfs_acl.c and provide a proper stub for the !CONFIG_XFS_POSIX_ACL case. Lift the flags check to the caller as it nicely fits in there. Signed-off-by: Christoph Hellwig Reviewed-by: Dave Chinner Reviewed-by: Chandan Rajendra Reviewed-by: Darrick J.
