From e45d7cb2356e6b59fe64da28324025cc6fcd3fbd Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Sat, 9 Jul 2022 10:56:06 -0700 Subject: xfs: use XFS_IFORK_Q to determine the presence of an xattr fork Modify xfs_ifork_ptr to return a NULL pointer if the caller asks for the attribute fork but i_forkoff is zero. This eliminates the ambiguity between i_forkoff and i_af.if_present, which should make it easier to understand the lifetime of attr forks. While we're at it, remove the if_present checks around calls to xfs_idestroy_fork and xfs_ifork_zap_attr since they can both handle attr forks that have already been torn down.
