From 8cde9f259c7d91d05b12cc68993a9643d6b4e45f Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 7 Jan 2020 15:25:38 -0800 Subject: [PATCH] xfs: also remove cached ACLs when removing the underlying attr We should not just invalidate the ACL when setting the underlying attribute, but also when removing it. The ioctl interface gets that right, but the normal xattr inteface skipped the xfs_forget_acl due to an early return. Signed-off-by: Christoph Hellwig Reviewed-by: Darrick J.
