Subject: [f2fs-dev] [PATCH] f2fs: compress: fix to print raw data size in error path of lz4 decompression
Date: Wed, 16 Mar 2022 18:20:00 +0800 [thread overview]
Message-ID: <20220316102000.3727130-1-chao@kernel.org> (raw)
In lz4_decompress_pages(), if size of decompressed data is not equal to
expected one, we should print the size rather than size of target buffer
for decompressed data, fix it.
