When user does not specify dump target explicitly, it's better to
dump to the "path" specified. That means after dump user enter into
1st kernel, can find vmcore in the "path". If that path is in root
fs, vmcore is stored in root fs. If separate disk is mounted on
any tier of "path", we just dump vmcore into the left path on the
left separate disk.
E.g in kdump.conf
path /mnt/nfs
in mount info,
/dev/vdb on /mnt type ext4 (rw,relatime,seclabel,data=ordered)
Then vmcore will be saved in /nfs of /dev/vdb.
In this patch, pass mount info to dracut in this case if separate
disk is mounted on any tier of "path".
Meanwhile introduce a function in kdump-lib.sh to check if any
target is specified.
v4->v5:
Per Vivek's comment, add a helper function is_fs_dump_target.
Then is_user_configured_dump_target is rewrite with these helper
functions.
v5->v7:
No v6 for this patch. Just use newly introduced function
is_fs_type_nfs in handle_default_dump_target.
