Sheng Yong c36ec00d7f erofs: add 'fsoffset' mount option to specify filesystem offset ... When attempting to use an archive file, such as APEX on android, as a file-backed mount source, it fails because EROFS image within the archive file does not start at offset 0. As a result, a loop or a dm device is still needed to attach the image file at an appropriate offset first. Similarly, if an EROFS image within a block device does not start at offset 0, it cannot be mounted directly either. To address this issue, this patch adds a new mount option `fsoffset=x' to accept a start offset for the primary device. The offset should be aligned to the block size. EROFS will add this offset before performing read requests.
