From 0a5b71d123ee41b244732fb04d224d36e9ccff84 Mon Sep 17 00:00:00 2001 From: Tao Liu Date: Sat, 8 Oct 2022 15:41:39 +0800 Subject: [PATCH] Add lvm2 thin provision dump target checker We need to check if a directory or a device is lvm2 thinp target. First, we use get_block_dump_target() to convert dump path into block device, then we check if the device is lvm2 thinp target by cmd lvs. is_lvm2_thinp_device is now located in kdump-lib-initramfs.sh, for it will be used in 2nd kernel. is_lvm2_thinp_dump_target is located in kdump-lib.sh, for it is only used in 1st kernel, and it has dependencies which exist in kdump-lib.sh.
