[PATCH] Check "default" option config in kdump.conf
by WANG Chao 04 Dec '14

04 Dec '14

"default" option only takes reboot/halt/poweroff/shell/dump_to_rootfs as its config value. Otherwise kdump service fails early.

[PATCH v3] kdump-initramfs-lib: Fix core_collector issue
by WANG Chao 04 Dec '14

04 Dec '14

In ssh or raw dump case, if user do not specify "core_collector" in kdump.conf, kdump will fail. Because global DEFAULT_CORE_COLLECTOR variable isn't applied to CORE_COLLECTOR. Now fix it and clean up the duplicate code in kdump.sh.
