Re: [PATCH 8/8] [PATCH v2] [CCID3]: Interface CCID3 code with newer Loss Intervals Database
| When interfacing we must make sure that ccid3 tfrc_lh_slab is created | and then tfrc_li_cachep is not needed. I'm doing this while keeping | the structure of the patches, i.e. one introducing, the other removing. | But we need to create tfrc_lh_slab if we want the tree to be bisectable. | | I'm doing this and keeping your Signed-off-line, please holler if you | disagree for some reason. If you are just shifting and reordering then that is fine with me. But it seems you mean a different patch since in this one there is no slab initialisation. The loss history and the RX/TX packet history slabs are all created in tfrc.c using the three different __init routines of the dccp_tfrc_lib. - To unsubscribe from this list: send the line unsubscribe dccp in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
CCID4 Tree Updated
This is to announce that the CCID4 tree at git://eden-feed.erg.abdn.ac.uk/dccp_exp [ccid4] has been updated with regard to the latest changes on the list. It compiles cleanly, also did some application-level testing (streaming). - To unsubscribe from this list: send the line unsubscribe dccp in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

If you are just shifting and reordering then that is fine with me. But it seems you mean a different patch since in this one there is no slab initialisation. This time around I'm not doing any reordering, just trying to use your patches as is, but adding this patch as-is produces a kernel that will crash, no? The loss history and the RX/TX packet history slabs are all created in tfrc.c using the three different __init routines of the dccp_tfrc_lib. Yes, the init routines are called and in turn they create the slab caches, but up to the patch [PATCH 8/8] [PATCH v2] [CCID3]: Interface CCID3 code with newer Loss Intervals Database the new li slab is not being created, no?
