From de1a9197af7f67a89f929dcadb8ceca8c3846b1c Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Fri, 30 Oct 2020 11:57:59 +0100 Subject: elf: Unify old and new format cache handling code in ld.so struct file_entry_new starts with the fields of struct file_entry, so the code can be shared if the size computation is made dynamic.
