The patch "xfs: create attr log item opcodes and formats for parent
pointers" now contains:
void
xfs_attr_defer_add(
struct xfs_da_args *args,
enum xfs_attr_defer_op op)
{
struct xfs_attr_intent *new;
unsigned int log_op = 0;
bool is_pptr = args->attr_filter & XFS_ATTR_PARENT;
if (is_pptr) {
ASSERT(xfs_has_parent(args->dp->i_mount));
ASSERT((args->attr_filter & ~XFS_ATTR_PARENT) != 0);
ASSERT(args->op_flags & XFS_DA_OP_LOGGED);
ASSERT(args->valuelen == sizeof(struct xfs_parent_rec));
}
new = kmem_cache_zalloc(xfs_attr_intent_cache,
GFP_NOFS | __GFP_NOFAIL);
new->xattri_da_args = args;
/* Compute log operation from the higher level op and namespace. */
switch (op) {
case XFS_ATTR_DEFER_SET:
if (is_pptr)
log_op = XFS_ATTRI_OP_FLAGS_PPTR_SET;
else
log_op = XFS_ATTRI_OP_FLAGS_SET;
break;
case XFS_ATTR_DEFER_REPLACE:
if (is_pptr)
log_op = XFS_ATTRI_OP_FLAGS_PPTR_REPLACE;
else
log_op = XFS_ATTRI_OP_FLAGS_REPLACE;
break;
case XFS_ATTR_DEFER_REMOVE:
if (is_pptr)
log_op = XFS_ATTRI_OP_FLAGS_PPTR_REMOVE;
else
log_op = XFS_ATTRI_OP_FLAGS_REMOVE;
break;
default:
ASSERT(0);
break;
}
new->xattri_op_flags = log_op;
/* Set up initial attr operation state. */
switch (log_op) {
case XFS_ATTRI_OP_FLAGS_PPTR_SET:
case XFS_ATTRI_OP_FLAGS_SET:
new->xattri_dela_state = xfs_attr_init_add_state(args);
break;
case XFS_ATTRI_OP_FLAGS_PPTR_REPLACE:
ASSERT(args->new_valuelen == args->valuelen);
new->xattri_dela_state = xfs_attr_init_replace_state(args);
break;
case XFS_ATTRI_OP_FLAGS_REPLACE:
new->xattri_dela_state = xfs_attr_init_replace_state(args);
break;
case XFS_ATTRI_OP_FLAGS_PPTR_REMOVE:
case XFS_ATTRI_OP_FLAGS_REMOVE:
new->xattri_dela_state = xfs_attr_init_remove_state(args);
break;
}
xfs_defer_add(args->trans, &new->xattri_list, &xfs_attr_defer_type);
trace_xfs_attr_defer_add(new->xattri_dela_state, args->dp);
}
and then we can drop this patch.
