[systemd-devel] siphash24 gives unmatched bloom_mask and bloom_filter?

[eshark77 at 163.com]

Hi, David
   I just modified the  src/libsystemd/sd-bus/test-bus-match.c. 
And you could add the following two lines in the bloom_add_data() in bus-bloom.c
         for (i = 0; i < size/sizeof(uint64_t); i++)
            log_info("bloom: filter[%d] = 0x%llx",i, filter[i]);

Thank you very much!
