reparent_resources() is duplicated in arch/microblaze/pci/pci-common.c
and arch/powerpc/kernel/pci-common.c, so move it to kernel/resource.c
so that it's shared. Later its code also need be updated using list_head
to replace singly linked list.

The struct resource uses singly linked list to link siblings, implemented
by pointer operation. Replace it with list_head for better code readability.
Based on this list_head replacement, it will be very easy to do reverse
iteration on iomem_resource's sibling list in later patch.
Besides, type
This patchset is doing:
1) Replace struct resource's sibling list from singly linked list to
list_head. Clearing out those pointer operation within singly linked
list for better code readability.
2) Based on list_head replacement, add a new function

Hi Dan,
Why is this needed ?
I can't see the real benefit, having the vma deferenced from the vm_fault
structure is not obfuscating the

Some test scripts have same function. So, let's cleanup
to stop the duplication by intoducing 'test/common' file.
Test scripts includes the common file to use the functions.
Masayoshi Mizuma (2):
test: add some helper function for test script
test: cleanup test scripts
test/blk-exhaust.sh
From: Masayoshi Mizuma
Some test scripts have same function. So, this patch introduces
the functions to 'test/common' new file.

kstrndup() takes care of '\0' terminator for the strings.
Use it here instead of kmemdup() + explicit terminating the input string.
