Most of the callers of erofs_read_metabuf() have the following form: block = erofs_blknr(sb, offset); off = erofs_blkoff(sb, offset); p = erofs_read_metabuf(...., erofs_pos(sb, block), ...); if (IS_ERR(p)) return PTR_ERR(p); q = p + off; // no further uses of p, block or off. The value passed to erofs_read_metabuf() is offset rounded down to block size, i.e. offset - off. Passing offset as-is would increase the return value by off in case of success and keep the return value unchanged in in case of error. In other words, the same could be achieved by q = erofs_read_metabuf(...., offset, ...); if (IS_ERR(q)) return PTR_ERR(q); This commit convert these simple cases.
