File kdump-fadump-add-udev-support.patch of Package kdump.21348
From: Hari Bathini <hbathini@linux.ibm.com> Subject: fadump: add udev event support for fadump References: bsc#1108170 Upstream: merged Git-commit: eb5784f6cb8368b346b9b52be66116fc5a47f720 Currently, the udev rules written in kdump package only support reloading kdump on memory/cpu hot add/remove operation. But this is needed as much for FADump as well. The rules were not updated to support fadump owing to lack of support in the kernel for re-registering FADump. This support is now added to kernel with commit 0823c68b054b ("powerpc/fadump: re-register firmware-assisted dump if already registered"). Update kdump udev rules to load fadump on memory/cpu DLPAR operations.
