[Crash-utility] crash version 4.0-4.12 is available
- Fix for the "kmem -n" command to handle the 2.6.24 kernel replacement
of the "node_online_map" nodemask with its appropriate entry in the
new "node_states[]" nodemask array. Without the patch, the per-node
zone data would not be displayed, and any commands depending upon
the node table data would be affected. (anderson(a)redhat.com)
- Fix for "kmem -p" on 2.6.24 x86_64 kernels that are configured with
CONFIG_SPARSEMEM_VMEMMAP, which use a virtually-mapped page struct
array. Without the patch, the virtual-to-physical translation of
each page structure was invalid, and "kmem -p" would display invalid
data. This would also affect other commands as well, such as the
output of "kmem -i", and the output of a "vtop" command on a
mapped
page address. Also, the virtual base address of the region is now
displayed by the "mach" command.

- Fix for the "dev" command's character device name string output to
recognize the change of the name structure member from a pointer
to an embedded string. Without the patch, 2.6.16 and later kernels
would display "(unknown)" character device names.

- Fix for the "kmem -[sS]" command to handle the 2.6.24 change to
the CONFIG_SLUB kmem_cache structure, which re-worked the manner
in which the per-cpu slabs get referenced. Without the patch,
the command would fail with several error messages of the type:
"kmem: page_to_nid: invalid page: ffff81003993f4b0".

- Fix for the "kmem -[fF]" command to handle the 2.6.24 kernel change
of the free_area struct, which replaced the singular linked list
of pages with 5 (MIGRATE_TYPES) linked lists. Without the patch,
the command would fail with the error message: "kmem: unrecognized
free_area struct size: 88". (anderson(a)redhat.com)
- Fix for the "runq" command to handle the 2.6.24 kernel change to
the CFS scheduler that introduced per-cpu init_cfs_rq structures
for task group scheduling. Without the patch, no queued tasks
were displayed, because the rb_root of queued tasks was being
taken from the embedded cfs_rq in each per-cpu runqueue.
