From c9a8adc15f9de110771156fdc85fb98533648a53 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Mon, 5 Jun 2023 19:06:42 +0200 Subject: Move dir_entry_xattr_t from libio to libsquashfs The structure and functions are renamed to sqfs_xattr_* instead, an additional helper is added to accept an encoded xattr. Documentation and unit test are added as well.
