This patch set backport patches from makedumpfile upstream, which provide
dry-run and show-stats options, to help estimate if there is enough free
space to save the vmcore in a target.
Tao Liu (3):
Add --dry-run option to prevent writing the dumpfile
Add shorthand --show-stats option to show report stats
Show write byte size in report messages

New subject: [PATCH 3/3] Show write byte size in report messages
Backport from upstream.
commit 0ef2ca6c9fa2f61f217a4bf5d7fd70f24e12b2eb
Author: Kazuhito Hagio <k-hagio-ab(a)nec.com>
Date: Thu Feb 4 16:29:06 2021 +0900
[PATCH] Show write byte size in report messages
Show write byte size in report messages. This value can be different
from the size of the actual file because of some holes on dumpfile
data structure.
$ makedumpfile --show-stats -l -d 1 vmcore dump.ld1
...
Total pages : 0x0000000000080000
Write bytes : 377686445
...
# ls -l dump.ld1
-rw------- 1 root root 377691573 Feb 4 16:28 dump.ld1
Note that this value should not be used with /proc/kcore to determine
how much disk space is needed for crash dump, because the real memory
usage when a crash occurs can vary widely.

Add shorthand --show-stats option to show report stats
