The tested\nfix is to simply add an else clause setting pctx-\u003eilen to 0 for the\nassoclen \u003d\u003d 0 case, so that get_data_to_compute() doesn\u0027t try doing\nthings its not supposed to.\n\nSigned-off-by: Jarod Wilson \u003cjarod@redhat.com\u003e\nAcked-by: Neil Horman \u003cnhorman@tuxdriver.com\u003e\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\n"
