attr -Rs 1234567890ad a< /dev/null

attr -Rs 1234567890af a< /dev/null
oops. the following steps are also needed - I took them out because I
thought they were unecessary:
# remove the attributes:
attr -Rr 1234567890ad a
attr -Rr 1234567890ae a
attr -Rr 1234567890af a
now we will assert
# the following remove will assert a debug kernel:
# XFS: Assertion failed: ip->i_d.di_nextents == 0, file: fs/xfs/xfs_inode.c,
