this appears to be basically the same patch as applied to 2.4.0t8 vs. t7
producing an Oops in dquot_transfer(). This issue can (at least) be
triggered by chown'ing a file on an (userquota && !groupquota) filesystem
from an user with unlimited quota to one who is restricted.
I've sent a fix for this to the diskquota-maintainer ([EMAIL PROTECTED])
and l-k yesterday. With a few lines offset the same patch should be
applicable to 2.2.18pre4 - but haven't tested in this context!
