Description of problem:
Anderson wrote kdump can support full dump or kernelpages only dump in
But in RHEL5.2 kernel-doc, kdump.txt says this function is in "TO DO" list. will
we bring this function into RHEL5.3?
in some of my cases, some servers has 16GB or more memory, a full dump will
create a huge file. It will cost 1-2 days to transfer it to redhat.
Some other customers want to protect their data, they wishes kdump not collect
the user-space pages. They know disk-dump can support it in RHEL4.
Could we implement it in RHEL5.3.
This has been implemented since GA iirc, using the makedumpfile utility, which
is configurable automatically through kdump using the core_collector option in
/etc/kdump.conf. See man makedumpfile (specifically the -d option) for details
