From aed35c78c6a51a4b4c37ebda5643d2246842fb74 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Fri, 8 Jul 2022 17:08:34 +0200 Subject: Fix: libfstree: actually use a full 32 bit hard link counter The squashfs on-disk format uses 32 bit link counters, but the fstree used 16 bit ones. Because the link count also includes child nodes, this artificially limited the number of entries in a directory to ~64k files. This patch removes the limit by switching libfstree to 32 bit counters.
