From: Colin Ian King <colin.king(a)canonical.com&gt; The functions create_namespace_pmem and create_namespace_blk are local to the source and do not need to be in global scope, so make them static. Cleans up sparse warnings: symbol 'create_namespace_pmem' was not declared. Should it be static? symbol 'create_namespace_blk' was not declared. Should it be static?
