Subject: [PATCH 3/4] erofs-utils: lib: fix rebuilding empty chunk-based files
Date: Thu, 17 Sep 2026 11:53:48 +0800 [thread overview]
Message-ID: <20260917035349.1339521-3-stopire@gmail.com> (raw)
In-Reply-To: <20260917035349.1339521-1-stopire@gmail.com>
Switch empty files to FLAT_PLAIN before setting u.i_blkaddr to
EROFS_NULL_ADDR, which would otherwise overwrite u.chunkformat.
Fixes: b0b1711d4611 ("erofs-utils: support building image with reserved space")
Assisted-by: Codex:gpt-6-astra
