Create a separate slab cache for struct xfs_attr_item objects, since we
can pack the (104-byte) intent items more tightly than we can with the
general slab cache objects. On x86, this means 39 intents per memory

The calling conventions of this function are a mess -- callers /can/
provide a pointer to a pointer to a state structure, but it's not
required, and as evidenced by the last two patches, the callers that do
weren't be careful enough about how to deal with an existing da state.
Push the allocation and freeing responsibilty to the callers, which
means that callers from the xattr node state machine steps now have the
visibility to allocate or free the da state structure as they please.
As a bonus, the node remove/add paths for larp-mode replaces can reset
the da state structure instead of freeing and immediately reallocating
it.

The NFSv3 CREATE and NFSv4 OPEN(CREATE) use cases are about to

As a first step, copy do_nfsd_create() to nfs3proc.c and remove

If a setxattr operation finds an xattr structure in leaf format, adding
the attr can fail due to lack of space and hence requires an upgrade to
node format. After this happens, we'll roll the transaction and
re-enter the state machine, at which time we need to perform a second
lookup of the attribute name to find its new location. This lookup
attaches a new da state structure to the xfs_attr_item but doesn't free

I think this is a consequence of xfs_attr_node_removename_setup
attaching a new da(btree) state to xfs_attr_item and never freeing it.
I /think/ it's the case that the remove paths could detach the da state
earlier in the remove state machine since nothing else accesses the
state. However, let's future-proof the new xattr code by adding a
catch-all when we free the xfs_attr_item to make sure we never leak the
da state.

Combination of LOOKUP_IS_SCOPED and NULL nd->root.mnt is impossible
after successful path_init(). All places where ->root.mnt might
become NULL do that only if LOOKUP_IS_SCOPED is not there and
path_init() itself can return success without setting nd->root
only if ND_ROOT_PRESET had been set (in which case nd->root
had been set by caller and never changed) or if the name had
been a relative one *and* none of the bits in LOOKUP_IS_SCOPED

Since all calls of legitimize_root() must be downstream of successful
