Subject: [B.A.T.M.A.N.] [PATCH] batman-adv: add sanity check when removing global tts
Date: Wed, 19 Oct 2011 10:28:26 +0200 [thread overview]
Message-ID: <20111019082826.GA31323@pandem0nium> (raw)
[-- Attachment #1: Type: text/plain, Size: 784 bytes --]
After removing the batman-adv module, the hash may be already gone
when tt_global_del_orig() tries to clean the hash. This patch adds
a sanity check to avoid this.
