Subject: [PATCH -next] dm btree: make symbol 'shadow_child' static
Date:   Fri, 21 May 2021 20:48:56 +0800

The sparse tool complains as follows:

drivers/md/persistent-data/dm-btree.c:696:5: warning:
 symbol 'shadow_child' was not declared. Should it be static?

This symbol is not used outside of dm-btree.c, so marks it static.
