From 438dcabb75d6b9b0e7f887befb753d1863f14deb Mon Sep 17 00:00:00 2001 From: Simon Goldschmidt Date: Tue, 26 Feb 2019 22:27:52 +0100 Subject: [PATCH] spl: add debug print for early malloc usage To find out how big the early malloc heap must be in SPL, add a debug print statement that dumps its usage before switching to relocated heap in spl_relocate_stack_gd() via CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN.
