The syzbot test case includes injecting memory allocation\nfailures, and it very much looks like xa_store() can fail one of its\nmemory allocations and end up with ->head being non-NULL even though no\nentries exist in the xarray.\n\nUntil this issue gets sorted out, work around it by attempting to\niterate entries in our xarray, and WARN_ON_ONCE() if one is found.",
