Subject: [PATCH 4/7] dyndbg: select ZPOOL,ZS_MALLOC in Kconfig.debug DYNAMIC_DEBUG_CORE
Date: Wed, 25 Nov 2020 12:36:23 -0700	[thread overview]
Message-ID: <20201125193626.2266995-5-jim.cromie@gmail.com> (raw)
In-Reply-To: <20201125193626.2266995-1-jim.cromie@gmail.com>

dyndbg will next need zs_malloc and friends, so add config reqs now,
to maybe avoid churny remakes later.

ZPOOL,ZSMALLOC are now required for DYNAMIC_DEBUG_CORE, as theyre
needed to get value (mem use reduction) from the upcoming
dyndbg/callsite split.

---

ZS_MALLOC is done with "depends on" instead of "select" to break a
recursive dependency.  I think this doesnt quite sort things out for
other config permutations, TBD.

-v2 fixup -> _CORE
