* quota linked list: user quotas and group quotas form two separate
* singly linked lists. ll_next stores uids or gids of next quotas in the
* linked list.
Given the uid/gid, how to calculate the quota file offsets for the corresponding
gfs2_quota structures on disk:
for user quotas, given uid,
offset = uid * sizeof(struct gfs2_quota);
for group quotas, given gid,
offset = (gid * sizeof(struct gfs2_quota)) + sizeof(struct gfs2_quota);
