I wanted to look at the "struct csched_private" of credit scheduler and gotthe contents of the "struct csched_private" of credit2. The debug informations of the hypervisor contain 2 entries <1><b185e>: Abbrev Number: 8 (DW_TAG_structure_type) <b185f> DW_AT_name : (indirect string, offset: 0x9d8d): csched_private and <1><c0677>: Abbrev Number: 25 (DW_TAG_structure_type) <c0678> DW_AT_name : (indirect string, offset: 0x9d8d): csched_privateThe first is credit and the second credit2. It seems in the crash command thesecond entry wins :-(.Maybe crash has the possibility somewhere to get access to the second structure (I couldn't find it) but for simplicity it would be better to have differentnames I think. Are there any reasons not to rename struct csched_private -> struct c2sched_private or whatever?No reasons at all -- the naming is an artifact of development. Feel free tosend a patch renaming it.I tried it once: http://lists.xen.org/archives/html/xen-devel/2013-02/msg02255.htmlJan didn't like it. It looks like he was only thinking about backtraces, not about cscope or about debugging core dumps. Jan, do you have another solution for those, or shall we go ahead and change the names? -George _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
