Description Dave Anderson 2017-09-29 18:14:47 UTC

Description of problem:

The RHEL7.5 errata version of the crash utility should be
rebased to the current upstream version, currently at version
crash-7.2.0.  There are several new features and other bug fixes
that have been applied to the upstream version make the tool 
significantly more useful than the current RHEL7.4 version.
This includes fixes and updates for the "kmem", "tree", "vtop",
"dis", "bt" and "task" commands, several s390x enhancements from IBM, 

Furthermore, crash-7.2.0 is required for 4.13 and later kernels,
and because of that, it would obviate the need to sustain the
current RHEL-ALT-7.4.Z branch of the crash utility.  Ideally
the RHEL7.5 version could be used for both RHEL7 and RHEL-ALT-7
instead of maintaining a separate RHEL-ALT-7 branch.

It is far more efficient, and far safer, to rebase the crash 
package than to attempt to selectively backport individual patches.
As the owner and upstream maintainer, one of my primary goals is,
and always has been, to maintain backwards-compatibility whenever 
new fixes or features are applied.  The risk of regression is 
less with a rebase than it would be with selective backports.

It should be noted that nothing goes into the upstream version 
without my approval.  I perform all my testing on Fedora and RHEL
kernel versions, where each individual change is meticulously 
tested against a sample set of RHEL3, RHEL4, RHEL5, RHEL6, RHEL7,
Fedora, and RHEL-ALT-7 kernels.
