Hi,
while debugging a vmcore with the crash tool I stumpled over a little problem.
I wanted to look at the "struct csched_private" of credit scheduler and got
the 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_private
The first is credit and the second credit2. It seems in the crash command the
second 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 different
names
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 to
send a patch renaming it.
I tried it once:

Jan didn't like it.
