Hi Dave, et al.,
Having hacked my way around the self-sabotage on the temp file:
> #define mWARN( _m, _a...) do { \
> FILE * _sv_fp = fp; \
> fp = stdout; \
> error(WARNING, _m, ##_a); \
> fp = _sv_fp; \
> } while (0)
That also removed the mysterious problem of having a duplicate error
message show up on the console.
My next problem is that I seem to be getting inconsistencies between
the data I can print and the data I can find mapping information about:
> crash> gdb set $tp = (struct cfs_trace_page *)0xffff8807fb590740
> crash> p $tp->page

So I can print out the page_t structure (renamed as cfs_page_t in Lustre)
at address 0xffff8807fb590740, but when I try to get kmem information about
it, it cannot find the page. What am I missing?
Thanks for hints/pointers! Regards, Bruce
