the kernel has dynamically downsized from the size indicated by the
debuginfo data. At this time, only "kmem_cache" and "task_struct"
structures that have been downsized are registered, but others may be
added in the future. If a downsized data structure is passed to gdb
for display, gdb will request a read of the "full" data structure,
which may flow into a memory region that was either filtered by
makedumpfile(8), or perhaps into non-existent memory, thereby killing
the generating command immediately due to a partial read. With this
patch, commands such as "struct" and "task" that reference downsized
data structures will have their reads flagged to return successfully
if partial read error occurs.

instructions. Without the patch, "dis [-f] <function>" may continue
beyond the end of a function, disassembling the memory that is in
between the target function and the next function.

correctly since crash-5.1.4. Without the patch, if the "g" alias
and the first argument are separated by one space, then the first
first character of that argument would get stripped prior to being
passed to the embedded gdb module.
