By the way, on further examination of the code it doesn't actually do
what's described in the case where the target name is large and the
moved-from name is small. Instead, it reports random garbage (usually
part of a name left over from some other dentry?) as far as I can tell:
from switch_names():
if (dname_external(target)) {
if (dname_external(dentry)) {
...
} else {
/*
* dentry:internal, target:external. Steal target's

*/
dentry->d_name.name = target->d_name.name;
target->d_name.name = target->d_iname;
... but target->d_iname could have anything in it, right?
