Subject: [PATCH 2/5] hw/core/loader: Use qemu_open() instead of open() in get_image_size()
Date: Thu, 16 Oct 2025 23:04:59 +0530	[thread overview]
Message-ID: <20251016173502.1261674-4-vishalc@linux.ibm.com> (raw)
In-Reply-To: <20251016173502.1261674-1-vishalc@linux.ibm.com>

Replace open() with qemu_open() which provides better error handling
via the Error object, automatically sets O_CLOEXEC, and supports FD
passing with /dev/fdset.

Remove redundant error_setg_file_open() call since qemu_open() now
handles error reporting internally.
