From 19e183b54528f11fafeca60fc6d0821e29ff281e Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Thu, 22 Dec 2022 18:12:50 +0000 Subject: elfcore: Add a cprm parameter to elf_core_extra_{phdrs,data_size} A subsequent fix for arm64 will use this parameter to parse the vma information from the snapshot created by dump_vma_snapshot() rather than traversing the vma list without the mmap_lock.
