This doesn't fix anything.  The first failure is:

#6  0x0000555555649979 in XAS_INVALID (xas=xas@entry=0x7ffff4a003a0)
    at ../shared/linux/../../../../include/linux/xarray.h:1434
#7  0x000055555564f545 in check_xas_retry (xa=xa@entry=0x55555591ba00 <array>)
--Type <RET> for more, q to quit, c to continue without paging--
    at ../../../lib/test_xarray.c:131
#8  0x0000555555663869 in xarray_checks () at ../../../lib/test_xarray.c:2221
#9  0x00005555556639ab in xarray_tests () at xarray.c:15

That has nothing to do with xa_destroy().  What on earth are you doing?

Anyway, I'm at LSFMM and it'a Saturday.  I shan't be looking at this
until the 27th.  There's clearly no urgency since you're the first one
to notice in six months.
