------------------------------------------------------
From: Nick Desaulniers <nick.desaulniers@xxxxxxxxx>
Subject: mm/zsmalloc.c: fix -Wunneeded-internal-declaration warning
is_first_page() is only called from the macro VM_BUG_ON_PAGE() which is
only compiled in as a runtime check when CONFIG_DEBUG_VM is set, otherwise
is checked at compile time and not actually compiled in.
Fixes the following warning, found with Clang:
mm/zsmalloc.c:472:12: warning: function 'is_first_page' is not needed and
will not be emitted [-Wunneeded-internal-declaration]
static int is_first_page(struct page *page)
