Subject: [PATCH 03/16] malloc: Move MTAG_MMAP_FLAGS definition
Date: Thu,  4 Mar 2021 16:31:01 +0000	[thread overview]
Message-ID: <f7cd6d47a7d32cb818e711f24e21f75b6e0231f1.1614874816.git.szabolcs.nagy@arm.com> (raw)
In-Reply-To: <cover.1614874816.git.szabolcs.nagy@arm.com>

This is only used internally in malloc.c, the extern declaration
was wrong, __mtag_mmap_flags has internal linkage.
