[PATCH 10/23] dax: Convert xas_store() to xas_store_noinit()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



All remaining users of xas_store() store non-NULL entries so xas_store()
and xas_store_noinit() are equivalent. Replace xas_store() with
xas_store_noinit().
