rhashtable: Fix potential crash on destroy in rhashtable_shrink The current being_destroyed check in rhashtable_expand is not enough since if we start a shrinking process after freeing all elements in the table that's also going to crash. This patch adds a being_destroyed check to the deferred worker thread so that we bail out as soon as we take the lock. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
