      NFSD: Traverse unconfirmed client through hash-table · 2b905635
      Kinglong Mee 提交于
      When stopping nfsd, I got BUG messages, and soft lockup messages,
      The problem is cuased by double rb_erase() in nfs4_state_destroy_net()
      and destroy_client().
      
      This patch just let nfsd traversing unconfirmed client through
      hash-table instead of rbtree.
