Subject: [PATCH 2/5] arm64/zImage: Remove unnecessary allocation for kernel_uncompressed_buf
Date: Fri, 5 May 2023 10:54:34 +0800 [thread overview]
Message-ID: <20230505025438.11943-3-piliu@redhat.com> (raw)
In-Reply-To: <20230505025438.11943-1-piliu@redhat.com>
Since slurp_decompress_file() allocates the buffer to hold the content
read from the file, no need to allocate the buffer again.
