  30 From:   Eric Sandeen <sandeen@redhat.com>
  31 Subject: [PATCH] xfs: don't wrap ID in xfs_dq_get_next_id
  32 Message-ID: <f52de68d-abe6-1960-c0ef-1d199346f689@redhat.com>
  33 Date:   Fri, 16 Dec 2016 18:05:20 -0600
  34
  35 The GETNEXTQOTA ioctl takes whatever ID is sent in,
  36 and looks for the next active quota for an user
  37 equal or higher to that ID.
  38
  39 But if we are at the maximum ID and then ask for the "next"
  40 one, we may wrap back to zero.  In this case, userspace
  41 may loop forever, because it will start querying again
  42 at zero.
  43
  44 We'll fix this in userspace as well, but for the kernel,
  45 return -ENOENT if we ask for the next quota ID
  46 past UINT_MAX so the caller knows to stop.
