Subject: [PATCH] erofs: fix misbehavior of unsupported chunk format check
Date: Wed, 22 Sep 2021 17:51:41 +0800 [thread overview]
Message-ID: <20210922095141.233938-1-hsiangkao@linux.alibaba.com> (raw)
Unsupported chunk format should be checked with
"if (vi->chunkformat & ~EROFS_CHUNK_FORMAT_ALL)"
Found when checking with 4k-byte blockmap (although currently mkfs
uses inode chunk indexes format by default.)
Fixes: c5aa903a59db ("erofs: support reading chunk-based uncompressed files")
