RE: [Crash-utility] user-space enhancements
Thanks. I gather that lkcd/lcrash was an earlier effort unrelated to crash. Is that
correct?

There was a group at IBM (Stefan Schlosser
<sschloss(a)de.ibm.com>)
a few years ago which set up stuff to generate
a elf corefile for a user space process for lcrash.
Stefan did that as diploma thesis in our department at IBM. The ugly
part was the swap file handling. The swap files had to be saved after a
dump in order to access all user space memory. We added the save
function in lcrash:
lcrash -S <swapdump>
to generate a dump-file containing all used swapped out pages of all
swap areas.
And we added an extra parameter <swapdump> when starting lcrash to
analyze the dump:
lcrash map.x dump.x kerntypes.x <swapdump>
Here the posting on the lkcd mailing list:

But the code was never integrated officially in lcrash.
