    Description

      BUG: unable to handle kernel NULL pointer dereference at 00000000000000f8
...
RIP: 0010:qmt_site_recalc_cb+0x2ec/0x780 [lquota]
...
[ffffa5564118fda0] cfs_hash_for_each_tight at ffffffffc0c72c81 [libcfs]
[ffffa5564118fe08] qmt_pool_recalc at ffffffffc142dec7 [lquota]
[ffffa5564118ff10] kthread at ffffffffb45043a6
[ffffa5564118ff50] ret_from_fork at ffffffffb4e00255

      The panic occurres due to an empty qit_lqes array after qmt_pool_lqes_lookup_spec. Sometimes it is possible if global lqe is not enforced.
